August 1987 THE RAINBOW
LETTERS TO THE
SysOp Stands up for a Clean Board
Editor:
I applaud your "Print//-2" column in the
April 1987 issue. The column discussed
copyright laws and the clubs, BBS and pen
pal listings provided by THE RAINBOW. 1 am
a SysOp of Lansing's CoCo BBS. Ever since
I began operating Benchboard BBS in 1984,
I've had to deal with ridicule from a few
users for attempting to run a "clean" board.
I've also had to deal with the mentalities
expressed by both SysOps mentioned in
your column; the "1 didn't know" type and
the "1 know it's OK because 1 got them from
another BBS" type.
1 appreciate the support of the Greater
Lansing Color Computer User's Group
(CCUG) and articles such as yours. Please
continue to remind those who "don't know,"
while maintaining THE rainbow's clubs,
BBS and pen pal listings. These listings
provide contact for the many computerists
who do respect copyright laws. , . „

Bir-Banger Rebuttal
Editor:
In the "CoCo Consultations" column of
the March 1987 issue. Page 151, a reader
used the expression "bit-banger" in a request
for information. This expression has been
used in a derogatory sense for some time by
columnists in THE RAINBOW as though the
serial port of the CoCo is in some way
inferior. As your readers seem to be starting
to use the expression, it is probably time to
set the record straight.
The RS-232 specification defines an
industry standard for serial data communi-
cations that is a bit-by-bit transmission and
reception standard. It does not matter
whether one uses a PIA or a UART to
produce those bits to provide the serial bit
stream. The UART produces other signals
as well that a modem's hardware and soft-
ware may expect; however, if the modem
and its software are designed carefully, it will
still operate with a simple bit stream satis-
factorily. What does matter a lot is the design
of the terminal software at each end of the
communications loop and the care used in
writing and tuning the time delay loops.
Super Color Terminal, by Dan Nelson
(Softlaw, VIP), is an example of quality
software that works reliably through the
CoCo serial port, in duplex, at baud rates
up to 4,800.
My two "old gray" CoCos run in a master-
coprocessor mode, communicating at 8,000
baud, through their serial ports. Addition-
ally, the transmit and receive routines in my
Kamelion [See March 1987, Page 141]
software for the C0C0/SC68OO8 combina-
tion operate reliably through the serial port,
at 4,800 baud, duplex, with a Tektronics
4105 color terminal.
So, you see, if unreliability is encountered
when using a well-designed modem, it is the
software, not the CoCo's PIA-driven serial
port that is not reliable above 300 baud.

Discovering CoCo Software
Editor:
Why don't Radio Shack stores sell THE
rainbow? I think the thing that hurts the
CoCo most is that many new CoCo owners
think the only programs available for the
Color Computer are the ROM packs and
disk software from Radio Shack. They fail
to see the super programs from Diecom
Products, Colorwarc and many other great
software dealers. I'm not trying to put down
Radio Shack (they did make this awesome
computer), I just wish people would quit
saying "Yeah, I got a Trash-80 Computer,
but their games are sorry." „

BACK TALK
multitasking capabilities are astounding.
However, there are a few of us who use the
CoCo in a multiuser mode and require the
capabilities Login provides.
We use a CoCo 2 with hard drive and two
DT-100 terminals as a point-of-sale system
in our store. The system operates under OS-
9 Level I and is written in BAS1C09. (Perfor-
mance rivals and often exceeds similar
systems provided by the three-letter and
other large companies.)
We are completing the conversions neces-
sary to run the system on the CoCo 3 under
Level II. One major stumbling block has
been the lack of restrictions to accessing
certain files. Everyone is super-user. Also,
should two salespersons write sales tickets
simultaneously, the printer will print both
sales tickets simultaneously, alternating
lines. To prevent this, we had to rewrite the
printer device descriptor making it non-
shareable which, in turn, required that some
of the associated software be rewritten. A
Login capability, normally part of OS-9,
would have alleviated these problems.

HINTS & TIPS
Editor:
I must disagree with Dale Puckett's
implied position that Login for OS-9 Level
II is superfluous. Admittedly, most users do
not require multiuser capabilities, and the
Editor:
I just received my May rainbow and, as
always, read it from cover to cover right
away. In it, two people ask about printer
codes for underlining using VIP Writer and
the Smith-Corona printer. Since I use both
in my home business, I thought I would help
if I can.
Smith-Corona L-1000 Printer Codes
Code 3 turns on underline — all words:
3=27 ;G9
Code 1 turns on underline — one word :
1=2?;90
Code 4 turns off both underlinings:
4=27; 82
Since I use two printers (the other is an
Epson LX-80), I have a list of codes for each
and load each one before doing any writing.
This also helps remind me which printer to
turn on and which to turn off. You must use
the "no print" comment (CLEAR-SHIFT+) in
front of anything you do not want printed.

The Button 'II Fool Ya
Editor:
The CoCo 3 with an analog RGB monitor
gives no indication when ii is turned on. Its
power button, when turned on, extends
farther out than the power button on a
CoCo I does when it is turned off. I recom-
mend that the computer plug be discon-
nected when inserting or extracting the disk
controller. Had I taken these precautions, I
would not have blown my controller within
15 minutes after having received it.
The chip most likely to be damaged in
CoCo disk controllers is the 7416. There are
two of them in the Disto controller. The
WDI773-PH can also be destroyed, but less
often. Since the cost of a 7416 chip is
currently about $2.40 from most electronics
parts distributors, it is a reasonably good
gamble to try replacing this chip before
sending the entire controller to be repaired
for a charge of about $30. , ,, .

COCO 3
Editor:
There are those who are worried about
RAINBOW covering mostly CoCo 3 in the
future, but I am sure what you give the most
attention to will be governed by what you
receive from your readers. We bought a
CoCo 3 as soon as it was available and are
enjoying it more with each new program
from your magazine. I do hope your guide
to OS-9 Level II will be helpful, as 1 couldn't
get anywhere on my own. _ _ . ,

Keyboard Substitution
Editor:
When I read your September '86 preview
of the CoCo 3 home computer, dreams of
complex new word processing and /or data-
base management, combined with fully
integrated graphics applications (running
concurrently under OS-9 Level II) floated in
my mind. Alas, Radio Shack kept the old
repulsive Model I and Apple 11+ compatible,
non-Selcctric keyboard.
It's incredible that they didn't implement
the excellent layout of the now-obsolete
IBM PCjr (the replacement one, not the
original Chiclet-type). It includes all the
necessary keys (and more), in a small,
portable, detachable, cordless, Selectric-
type unit.
Now, I wonder, is there any way to
interface a PCjr (or Compatible) keyboard
to the CoCo 3 and thus solve Tandy's
mistake? Then it would be simple to write
a device-driver under OS-9 to gain access to
it. I know many people who would sell their
PCjr keyboards. Surely this could make the
CoCo 3 Number One in the home computer
arena. Long live CoCo!

Program Wish List
Editor:
I am looking for a program to use with
my 64K ECB CoCo 2, C-Itoh Prowriter 85 1
printer, and twin Digital drives. I am a sales
manager with 470 part-time and full-time
real estate agents and have to keep a running
roster of them that can be updated period-
ically. I am currently using a program called
Label III by Owl's Nest Software, but it has
limitations that make it difficult to operate.
The program I need must do the following:
1. Store names, addresses (street, city, and
ZIP codes with a provision for an extra
line) and phone numbers.
2. Sort quickly through the files (auto-
loading files as it sorts). Search by last
name (by ZIP and first name would be
nice, too).
3. Print files on fan-fold paper "3 wide" and
be able to stop at end of page and start
at the top of the next page.
4. Print files on adhesive mailing labels.
5. Store large amounts of files (400 to 600).
It is OK to refer back and forth to the disk
automatically.

Board Systems" in your May issue. I have
been wanting to set up a bulletin board for
a long time and have called all over the area
looking for one, but haven't been able to find
one. I see that there are a lot of them listed
here in your magazine. Could someone tell
me where I can purchase a BBS program?

VIP Frustrations
Editor:
1 am the happy owner of a new CoCo 3.
It's been a long time coming and I sure like
it. However, I have the entire VIP series and
none of it works on my new CoCo. I have
been hoping for months that a patch would
be published in THE RAINBOW. I've read that
a patch is on Delphi, but 1 can't get there
because I have VIP Terminal. Can anyone
out there help me?
Also, can anyone tell me how many CoCo
3s have been sold so far? Now that our
favorite computer has the memory that the
big guys do, will we gel programs like Lotus,
dBASE. /Vi, etc.? _ . ,..,,.

All Done With Mirrors
Editor:
I was paging through an electronics
magazine and read about someone who was
able to interface the Commodore 64
computer to drive digital radio control
airplane servos. I was impressed with the
article, as it involved a Helium-Neon laser
and the ability to store coordinates input
from joysticks to later drive the servos in the
desired sequence. Mirrors were hooked onto
the servos and a rather impressive laser light
show followed.
I have heard that my CoCo is the best
there is and I certainly believe it can outper-
form any C-64 on the street. My question is:
Can anyone tell me of a source or article in

INFORMATION PLEASE
Editor:
I have a 64K CoCo ROM Color BASIC 1.2,
Disk ECB 1.1, a CCR-81 cassette, Modem
IB, a Smith-Corona SE-200 with messenger
module and a Line Printer VII. I have
Version 1.0 of Elite-home and would really
like to be able to use it as it's advertised in
the RAINBOW. However, after loading 92
albums in the records file 1 got an IE Error.
I called Elite Software, was told no one else
had reported such a problem, and to return
the disks and they would see what they could
do.
A few days later, I received new disks in
the mail and, after backing up a set to work
from, I started using the Checks program.
After loading 184 checks, I got an IE Error.
I called Elite Software, who called me back
a couple of days later and told me 1 must
have removed the disk from the drive
without exiting the program properly.
I formatted another disk and started over.
I had been at the keyboard continuously the
entire time and the disk had definitely not
been removed from the drive. 1 again got an
IE Error after 184 entries. I called Elite and
was told the only possible way the IE Error
could occur was if I had pulled the disk out
without following the properexit procedure.
I denied pulling out the disk and was told
I must have pulled it out without noticing.
I did my print free (0) on both disks, and
on the records disk found that Records look
10 granules (which left me with 8 granules
free) and the Checks disk took 1 1 granules
(which left me with granules free). I tried
deleting other programs on both disks to
gain room, but it didn't work. Neither
program will take any more entries. My
questions are:
1. What am I doing wrong?
2. How can I correct it?
3. Can I use a third disk for specific fields
(e.g., checks, records, etc.)? If so, how do
I do it?
4. Is there anyone out there who has had and
solved similar problems?

Poke Preservation
Editor:
Being a novice CoCo owner is really a
ball. I've had my CoCo 2 for two months.
64K is plenty of memory for me right now,
but I've got a couple of questions about
some pokes and peeks I have been reading
about in the rainbow's last two issues.
I have a DMP-130 printer and it will
accept up to 2400 baud. The higher speeds
that are achieved at this baud rate are great
when I have written a program I want to
print out, bui how do I use this faster rate
when using a program pack like Color
Scripsill
I realize POKE 150,18 will do the trick
while programming, but what can I do to
keep this poke intact after inserting the
cartridge? The computer always wants to
drop back to its normal rate. Also, when I
PEEK 150, my CoCo 2 prints BB, not 87 like
you would expect. .... , „ „,

The Upgrade Dilemma
Editor:
Is it worth upgrading to a better, eight-bit
machine (CoCo 3) when there arc 16-bit
machines that don't cost much more? When
I speak of 16-bil machines, I don't mean a
Tandy 1000 or IBM PC. I am convinced an
OS-9 Level II CoCo 3 is better than these.
I am interested in the new MC68000-based
computers, like the Atari ST and Amiga.
How important is CPU clock speed? 1 love
my 64K. CoCo 2 and would like to love a
CoCo 3, but 1 have reservations.

Editor:
Is there anyone out there in CoCo land
who can tell me how to gel my CoCo 2 to
talk without any additional hardware? I
have seen many programs advertised that
say they have good quality speech, and the
speech is made possible through program-

Speedy Disk Delivery
Editor:
T & D Software should be congratulated
on its expedient service and reliability. It is
the only company out of several which
promptly sent software as part of a "free
software" campaign in conjunction with my
subscription order to THE rainbow. Orders
to T & D are filled quickly and often arrive
within two weeks. Recently, 1 experienced
trouble with some disks and returned them
for replacements. The new disks arrived the
same week! It is refreshing to find a business
that conducts "good business" — and T &
D accomplishes that task. , „.

An Assortment of Support
Editor:
I would like to lake this opportunity to
thank all the RAINBOW staff for bringing
such a fine publication to the CoCo world.
1 would also like to pass on special thanks
to Greg Miller and Erik Gavriluk for taking
the time out of their day to talk to fellow
users about seemingly trivial bits of CoCo
information. These are two very talented
programmers, and I appreciate very much
what Ihcy are doing for the CoCo world.
More thanks are in order for Computize's
service department, which has been very
friendly and helpful every lime I've called.
Finally, my hat is off to Mr. B.J. Chamb-
less and Computcrware for their long-term
and continued support of the CoCo. I
bought Magic of Zanth [See March 1987.
Page 140] and Ramdisk from them — two
great programs for the CoCo 3^ ^^

RAINBOWfest Raves
Editor:
We want to express sincere thanks to two
organizations:
First, to THE RAINBOW, for sponsoring the
Chicago RAINBOWfest. It was amazing to
see so many people in one place all dedicated
to a computer that so few people seem to
know about. (My wife likened it to the
Dayton Hamvcntion, and she was right!) All
the vendors and RAINBOW people we met
were just great, and we certainly intend to
return next year. (And yes, we did pig out
on software, not to mention hardware!)
Second, our thanks to the Elliotts at HJL
Products. We bought an HJL Numbcrjack
at RAINBOWfest, and had trouble getting
it to work. A letter to HJL brought a very
prompt, helpful answer, but when that
didn't work, a phone call (on their quarter,
yet!) got the information we needed. Sup-
port like this is hard to find these days, but
HJL really came through, and we thank
them for it. „ . , ... ,

Some Seventh
Year Changes
All's well that ends well.
William Shakespeare wrote it. Wendy Falk said it.
For those of you who read this space last month, 1 have news to
report. Sacy has been found.
Sacy is my eldest daughter's (Soft And CuddlY) teddy bear, who
turned up missing when she came home from an around-the-world
educational semester aboard ship. Somehow, Wendy's tote bag was
lost — and with it her 17 rolls of film, a number of presents and
Sacy.
Wendy is 20 and Sacy is 17, so you can imagine how upset she
was. After a couple of weeks of hoping he might turn up somehow,
Sacy had to be decreed lost. It was depressing. 1 wrote about it last
month. And one of the things 1 said was that it was a shame Sacy
would miss our Sixth Anniversary issue of the rainbow because it
would be the first one he had missed.
As it turned out, Sacy was on hand after all. Just a couple of days
after we went to press with the July issue and the Saga of Sacy, Wendy
got a letter from Delta Air Lines. They had a bag in Atlanta lost
and found, they wrote. If she could identify it, they would send it
to her.
Wendy didn't fly on Delta, but they apparently ended up with her
bag all the same. Her first question when she called Delta was
whether Sacy was safe. He was. And it was Sacy's presence that
seemed to be adequate to "identify" her lost tote bag.
We're not sure exactly how Sacy ended up in Atlanta or on Delta,
but we do know that Sacy arrived on the late flight from Atlanta
and Wendy was there to meet him. He's home now, and all the film
has been developed and pictures looked at many times already.
Just this evening I came home with the first copy of the
Anniversary Issue. Sacy was there to look it over, too. Everyone
was glad.

Thanks, Delta Air Lines. I guess
sometimes it helps to wish on a Rain-
bow.
Year Seven of THE RAINBOW brings
some changes.
Jim Reed, who has been managing
editor for many years, is moving to a
new position as assistant vice president
of programs and projects for our parent
firm, Falsoft, Inc, and Jutta Kapf-
hammer — who has been Number Two
to Jim for several years — takes over as
managing editor.
Expect to see some changes. Jutta
comes with a charge to spruce things up
a bit, both as far as content is concerned
and, with art director Heidi Maxedon,
will be looking at new design-type
things as well.
Jim will be in charge of a number of
special things — some new and some
that we hope to expand. He will, of
course, as executive editor, continue to
work with and advise me directly on this
magazine, in addition to our other
publications.
There are a number of other changes
associated with all of this, of course, but
they should not really affect the way you
relate to the magazine.
One other change, which may affect
a number of you, is in our advertising
area. Cindy Shackleford, who has run
our West Coast operation for a number
"Year Seven of
THE RAINBOW
brings some
changes. "
of years — first as an employee and then
as an independent representative — has
decided to seek another opportunity.
As a result, we have decided to move
all of the advertising territory that
Cindy formerly had into our own office
here in Prospect. If you are interested
in advertising and are in the western
part of the United States, you can now
get information from Belinda Kirby
here. Her number is (502) 228-4497.
Those who have worked with Kim
Vincent and Jack Garland are unaf-
fected by any of this.
1 know you will want to wish Jim,
Jutta, Cindy and Belinda well in their
new ventures.
By way of "finally," I've been asked
to point out two important things here.
The first is that our new OS-9 book,
expected to be ready very soon now, is
available from us only on a pre-order
basis. We are not planning to print more
copies of the book than for which we
have orders on hand when we "go to
press." So, if you want one, please order
it in advance.
Also, and very important, please fill
out (or photocopy and fill out) the
Color Computer Hall of Fame ballot on
Page 109 of the July issue. And, please,
only one ballot per nominator. This is
a special program we are planning in
conjunction with one of our future
RAIN BOW fests, and we want everyone
to have a chance to make nominations.

Jim Reed jumping off . . .
Jutta Kapfhammer coming on . . .
and Rainbow train keeps rollin' .
mthe first installment of my "Building A Rainbow" column, which began
in the April 1983 issue, I compared the creation of each month's issue
of THE RAINBOW to a train. I also explained that, at a certain point
in time, even though my heart remained with "those still on board" as the
"Production Express" clattered on down the line toward "Printer's Station," I
would have to jump off, roll down the bank and get about the process of forming
the next month's "train."
After 55 of these monthly tumbles, this time I'm not forming up another
trainload of material as this issue's caboose disappears into the distance. In fact,
the September RAINBOW is already chugging along the production line with Jutta
Kapfhammer at the controls. She's been appointed the new managing editor of
THE RAINBOW.
We were still in that crowded, former-beauty-salon of a RAINBOW office when
German-born, but American-raised Jutta (pronounce that "Utah") joined the staff
in February of 1983. So, even though she's only 28, Jutta's an "old-timer" by
RAINBOW standards. She's been our submissions editor for four years and for the
past year has also supervised editorial production for all of our publications. Thus,
becoming RAINBOW managing editor, while hard-earned, is but one more feather
in her Falsoft cap.
For those who don't know, the managing editor is the one who actually decides
what will be in THE RAINBOW, based on broad general guidelines established by
editor and publisher Lonnie Falk. Thus, each month, Jutta will make the selection
of specific articles to fit the monthly theme as well as "book" a variety of material
to ensure a balanced "editorial mix." She will then oversee the entire editorial
process, from "putting out fires" to making decisions about style and content, until
it's time for her to "jump off the train" and start forming yet another issue. Given
the same dedicated support, enthusiastic encouragement and enduring patience
that it has been my good fortune to receive from readers and contributors alike,
I am sure Jutta will find the challenge a rewarding one, too.
No, no gold watch for me yet. I'm simply going to be exploring and pursuing
some new avenues here at Falsoft as assistant vice president for programs and
projects. As executive editor, I'll retain a general oversight responsibility for the
editorial content of all Falsoft publications and, as groups manager on Delphi,
I'll be online almost every evening, as I am no w. In fact, many of you will be hearing
from me more often than before. So, no goodbyes are in order, but it's impossible
to say thank you too often and I want to use this juncture as an opportunity to
express my appreciation to all of you, too numerous to mention individually, for
helping us "Build a Rainbow" each month over the 4>/ 2 years of my tenure as
managing editor. 1 like to think that, together, we met the goal of "something for
everyone, and some things for everybody."
Thank you, CoCo Community. I'll miss the rumble, the rhythm and the roar
of the monthly train ride, but look for me waving at the crossing whenever the
"Rainbow Special" whistle blows. As it was when I first began, "my heart is with
those still on board," and I'm proud to be a part of it all.
Finally, the same invitation I extended in that very first "Building A Rainbow":
"If you aren't among those who have a year 'round pass to THE RAINBOW'S train
load of top-flight articles and programs, I hope you'll pull out the subscription
card and climb aboard."
Let's keep in touch, keep working together and keep following THE RAINBOW.
— Jim Reed

you are successful in completing the grid, another grid will
be dealt out, and a bonus score will be awarded for the
number of turns left upon completion of the grid.
After you load and run the program, the screen shows
the main title and the message "Building Graphics" in the
center of the screen. After a few seconds, the main playing
grid appears showing the 40-card grid, the score set at 0,
and the turn indicator set at 60. You are now ready to start
playing the game.
Use the digits (0 to 9) on the keyboard to enter the card
numbers you want to look at. Two cards must be selected
for each turn. The number of the card chosen must be from
01 to 40. For example, if you want to see the two cards
numbered 1 and 02. type 01, and after that card is revealed,
type 02 to reveal the second card. A tone sounds for every
key pressed. A high-pitched tone indicates that your entry
was accepted, and a second key may be pressed. If a low
tone sounds after you enter a two-digit number, this
indicates that your entry was rejected. You may now enter
another two-digit number. Typing any letter resets the
keying sequence in case you type a wrong number by
mistake.
If the two cards revealed are not a match, the computer
lets you examine them for about one second. Your turn
indicator will then be decremented by one, and the cards
will be turned face down again. At this point, you may make
another selection.
When you select two cards that match identically, the
computer removes them from the grid, you are scored for
the pair, and the turn indicator is decremented by one. At
this point, you may make another selection.
If you complete all 20 pairs of the grid within the allowed
amount of turns, you are scored a bonus of 10 points for
each turn left on the turn indicator and dealt a new grid
of 20 pairs, and your turn indicator is set with five fewer
turns than the previous round.
A player may play many rounds. The more rounds a
player completes, the harder it becomes, since there are
fewer turns allowed to complete the grid.
When a player runs out of turns on the turn indicator,
the computer reveals the entire grid, your total score is
displayed on the score board, and the turn indicator will

THE RAINBOW August 1987
the Color Computer Word Processor
3 display formats: 51/64/85
columns x 24 lines
True lower case characters
User-friendly full-screen
editor
Right justification
Easy hyphenation
Drives any printer
Embedded format and
control codes
Runs in 16K, 32K, or 64K
Menu-driven disk and
cassette I/O
No hardware modifications
required
THE ORIGINAL
Simply slated, Telewriter is the most powerful
word processor you can buy for the TRS-80
Color Computer. The original Telewriter has
received rave reviews in every major Color
Computer and TRS-80 magazine, as well as
enthusiastic praise from thousands of satisfied
owners. And rightly so.
The standard Color Computer display of 32
characters by 16 lines without lower case is
simply inadequate for serious word processing.
The checkerboard letters and tiny lines give you
no feel for how your writing looks or reads.
Telewriter gives the Color Computer a 51
column by 24 line screen display with true
lower case characters. So a Telewriter screen
looks like a printed page, with a good chunk of
text on screen at one time. In fact, more on
screen text than you'd get with Apple II, Atari,
TI, Vic or TRS-80 Model III.
On top of that, the sophisticated Telewriter
full-screen editor is so simple to use. it makes
writing fun. With single-letter mnemonic
commands, and menu-driven I/O and
formatting, Telewriter surpasses all others for
user friendliness and pure power.
Telewriter's chain printing feature means that
the size of your text is never limited by the
amount of memory you have, and Telewriter's
advanced cassette handler gives you a powerful
word processor without the major additional
cost of a disk.
...one of I he best programs for the Color
Computer I have seen...
— Color Computer News, Jan. 1982
TELEWRITER-64
But now we've added more power to
Telewriter. Not just bells and whistles, but
major features that give you total control over
your writing. We call this new supercharged
version Telewriter-64. For two reasons.
64K COMPATIBLE
Telewriter-64 runs fully in any Color Computer
— I6K, 32K, or 64K, with or without Extended
Basic, with disk or cassette or both. It
automatically configures itself to take optimum
advantage of all available memory. That means
that when you upgrade your memory, the
Telewriter-64 text buffer grows accordingly. In
a 64K cassette based system, for example, you
get about 40K of memory to store text. So you
don't need disk or FLEX to put all your 64K
to work immediately.
64 COLUMNS (AND 85!)
Besides the original 51 column screen,
Telewriter-64 now gives you 2 additional high-
density displays: 64 x 24 and 85 x 24!! Both
high density modes provide all the standard
Telewriter editing capabilities, and you can
switch instantly to any of the 3 formats with a
single control key command.
The 51 x 24 display is clear and crisp on the
screen. The two high density modes are more
crowded and less easily readable, but they are
perfect for showing you the exact layout of
your printed page, all on the screen at one
lime. Compare this with cumbersome
"windows" that show you only fragments at a
time and don't even allow editing.
RIGHT JUSTIFICATION &
HYPHENATION
One outstanding advantage of the full-width
screen display is that you can now set the
screen width to match the width of your
printed page, so that "what you see is what
you get." This makes exact alignment of
columns possible and it makes hyphenation
simple.
Since short lines are the reason for the large
spaces often found in standard right justified
text, and since hyphenation is the most
effective way to eliminate short lines,
Telewriter-64 can now promise you some of the
best looking right justification you can get on
the Color Computer.
FEATURES & SPECIFICATIONS:
Printing and formatting: Drives any printer
(LPVII/VI1I, DMP-100/200, Epson. Okidata,
Cenironics, NEC, C. Iloh, Smiih-Corona,
Terminel. etc).
Embedded control codes give full dynamic access to
intelligent printer features like: underlining,
subscript, superscript, variable font and type size, dol-
graphics, etc.
Dynamic (embedded) format controls for: top.
bottom, and left margins; line length, lines per page,
line spacing, new page, change page numbering,
conditional new page, enable/disable justification.
Menu-driven control of these parameters, as well as:
pause at page bottom, page numbering, baud raie (so
you can run your printer at top speed), and Epson
font. "Typewriter" feature sends typed lines directly
to your printer, and Direct mode sends control codes
right from the keyboard. Special Epson driver
simplifies use with MX-80.
Supports single and multi-line herders and automatic
centering. Print or save all or any section of the text
buffer. Chain print any number of files from cassette
or disk.
File and I/O Features: ASCII format files —
create and edit BASIC, Assembly, Pascal, and C
programs, Smart Terminal files (for uploading or
downloading), even text files from other word
processors. Compatible with spelling checkers (like
Spell 'n Fix).
Cassette verify command for su r e saves. Cassette auto-
retry means you type a load command only once no
matter where you are in the tape.
Read in. save, partial save, and append files with disk
and/or cassette. For disk: print directory with free
space to screen or printer, kill and rename files, set
default drive. Easily customized to the number of
drives in the system.
Editing features: Fast, full-screen editor with
wordwrap, block copy, block move, block delete, line
delete, global search and replace (or delete), wild card
search, fast auto-repeat cursor, fast scrolling, cursor
up, down, right, left, begin line, end line, top of text,
bottom of text; page forward, page backward, align
text, tabs, choice of buff or green background,
complete error protection, line counter, word counter,
space left, current file name, default drive in effect,
set line length on screen.
Insert or delete text anywhere on the screen without
changing "modes." This fast "free-form" editor
provides maximum ease of use. Everything you do
appears immediately on the screen in front of you.
Commands require only a single key or a single key
plus CLEAR.
. . . truly a stale of the art word processor. . .
outstanding in every respect.

Circuit Solution
When my tape recorder began giving me numerous
I/O Errors, I began to look for the cause. It appears
the dropping resistor in the aux input circuit of the
recorder had "gone high." This resulted in marginal
program saves. I replaced the resistor with one of the
proper value and all is well now. So, if you are
technically minded and the usual head alignment
adjustment doesn't do the trick, you might check for
this possibility. Theodore Looman

wtjAr Snake is a colorful game with
sound effects the whole family can enjoy,
You lead a snake around on the screen
looking For root beer, avoiding snake pits
and tying your snake into a knot. It
requires a 32K. Color Computer, a disk drive, and. as
an option, a joystick.
Type in the program from the listing and save ii to
your disk as SNEAKY. Be careful typing in lines 780 on,
as these lines contain the data needed to generate t In-
machine language portion of Sneaky Snake. Most of
the program is written in BASIC, but where quick
response is needed, machine language is used.
When you've copied Sneaky Snake onto your disk.
plug a joystick into the left joystick port (if you don't
have a joystick, you can elect to use the arrow keys
on the keyboard) then type RUN "SNEAKY" to start the
program. The screen will display the opening graphics
while the computer pokes in the machine language
program. Once the machine language program is in
memory, the rules and objectives of Sneaky Snake will
be displayed. Follow the instructions on the screen.
In general, the rules and objectives are to guide your
snake around on the screen using the joystick (01
keyboard), trying to lead the snake to the little blue-
mugs of root beer, avoiding the red snake pits. Hitting
a mug of root beer causes your snake to grow one body
length; hitting a snake pit causes your snake to shrink
one body length. The game ends if you run your snake
into a wall (outside edges of the play field) or lie your
snake into a knot (run the snake over itself). As you
will quickly learn, short snakes are easy to guide
around the screen, but long snakes can be difficult
I hope you enjoy Sneaky Snake. Be careful about
who you let play with the game, espe-
cially with joysticks. I lost two
joysticks when a frustrated friend
violently tried to avoid
running his snake
into a wall; funnji how the
"siick" doesn't bend aftei it reaches the end of its
travel. □

EDUCATION OVERVIEW
Approaches for
Lifelong Learning
By Michael Plog, Ph.D.
Rainbow Contributing Editor
Too often, we think of education
as something only for young
people. Sometimes we expand
our definition of education to college
students. The truth is that we learn at
any age, indeed at all ages. Instead of
thinking just about young people, con-
sider for a moment the adult learner,
especially the adult in need of computer
education.
Adult learners come in all types. For
example, many businesses offer
computer training for employees. Most
of these programs are oriented toward
specific applications, such as word
processing, database manipulation,
spreadsheets, or a general orientation to
computers. Many times, the learner
(company employee) is only taught
enough to start a computer, run the
specific application, and get out of the
task. In some cases, training is severely
limited to job-specific applications. For
example, some businesses only want
employees to update information in a
database file. Training is limited only to
how updating is done. There is no
broader learning about databases in
general or about how the machine
works.
This limited type of training serves a
Michael Plog received his doctorate
degree from the University of Illinois.
He has taught social studies in high
school, worked in the central office of
a school district and is currently em-
ployed at the Illinois State Board of
Education.
purpose for the business — employees
can now complete the tasks assigned to
them. It is not, however, much in the
way of adult education. The purpose of
adult education is the same as the
purpose of education for children: to
increase the knowledge level of the
learner and provide a set of skills that
can be used in a variety of situations.
Thus, this training is not true education.
There are millions of people who
entered the world of computers late. In
my own case, it has been over two
decades since I was in high school.
When 1 went to high school and college,
computers were discussed, but only as
powerful machines available to a few
and understood by even fewer. I know
some people who did not have the
opportunity to learn about computers
— when micros were on the market —
until they were retired!
There are many adults who want to
learn some general information about
computers, master a few applications,
or just increase their knowledge in some
specific area. These people represent the
need for adult education. Different
options exist to satisfy the need. All
have advantages; all have disadvan-
tages.
Most adults learn about computers
by the informal method. It is impossible
to talk with adult computer enthusiasts
for very long without hearing the phrase
"self-taught." Some people say it with
pride; some people say it with an apol-
ogy. The fact of the matter is that most
adult computer users are indeed self-
taught in many aspects of their ma-
chines. The idea of "self-taught" is a
little deceptive, however. Many people
have tutors — friends or relatives who
provide the basic instruction necessary
for continuing education to occur. After
the initial introduction, the computer
user becomes truly self-taught, learning
from books and trial and error.
This approach to computer knowl-
edge is not without merit. People lend
to learn more and faster when a topic
interests them. Informal learning also
centers very quickly on specific areas of
major importance to the learner. For
example, a person wants to learn about
spreadsheets. After a period of agony
and review, a spreadsheet is purchased.
The user quickly becomes familiar with
that package and with spreadsheets in
general.
Informal learning does not necessar-
ily mean reliance only on self. Many
computer users have friends who pass
on information and "tricks" about
manipulating the machines. Informa-
tion is shared freely among hobbyists.
The problem is that learning is spotty
and incomplete. The informal learner
misses many of the details, some of
which may be important.
One aspect of informal learning is
information shared at conferences.
Some people attend RAINBOWfest
primarily to talk to other users with
similar problems or to ask questions of
those with more experience.
There are other options for adult
learners besides the informal method.

The Best
The indispensable
THE RAINBOW is the biggest, best, brightest and
most comprehensive publication a happy CoCo
ever had! THE RAINBOW features more programs,
more information and more in-depth treatment of
the Tandy Color Computer than any other source.
A monthly issue contains more than 200 pages
and up to two dozen programs, 14 regular columns
and as many as 20 product reviews. And advertise-
ments: THE RAINBOW is known as the medium for
advertisers — which means every month it has a
wealth of information unavailable anywhere else
about new productsl Hundreds of programs are
advertised in its pages each month.
Every single issue of THE RAINBOW covers the
wide spectrum of interests in the Tandy Color
Computer — from beginners' tutorials and arcade
games to telecommunications and business and
finance programs. Helpful utilities and do-it-
yourself hardware projects make it easy and fun to
expand your CoCo's capabilities. And, monthly
reviews by independent reader reviewers take the
guesswork out of buying new software and hard-
ware products.
Join the tens of thousands who have found THE
RAINBOW to be an absolute necessity for their
CoCo. With all this going for it, is it surprising that
more than 90 percent of THE RAINBOW subscrib-
ers renew their subscriptions? We're willing to bet
that, a year from now, you'll be doing the same.

bmputer conferences also provide a
lore formal lype of education through
orkshops and presentations. Some of
le presentations deal with very specific
pplications, such as database manage-
icnt or spreadsheets.
Other, less informal, training is pro-
'ed by equipment dealers. Tandy still
jllers classes through Computer Cen-
ers for people who buy Tandy equip-
nent. The learner must pay a fee for
hese classes, but gets continuing sup-
lOrt (including telephone support) from
local Center. Other dealers may also
wide training for local markets, but
Tandy training is a national institu-
n.
Vlany adult learners have discovered
-n-credit courses at community (two-
ear) colleges. In most states, these
istitutions have continuing education
adults. Community college admin-
rations have discovered that comput-
education is a hot-selling topic at
resent. All types of students will enroll
i computer classes. Classes are typi-
;ly for specific applications, such as
^S1C instruction or word processing,
addition, most community colleges
fcr a course in beginning computer
literacy. The beauty of this somewhat
formal education for adult learners is
that tuition is often inexpensive, and
community colleges are often easy to get
to.
"No matter
how much you
know about
your computer,
there is still
more to learn. "
However, adult learners are not lim-
ited to community colleges for formal
instruction about computers. Private
firms are rapidly getting into the act,
also. In most towns, you can find
private instructors offering classes in
computer applications. Adults can
attend classes on a variety of topics.
from computer literacy to detailed
training in specific software packages.
Fees for these courses range from down-
right cheap to outrageous.
Formal instruction is even offered by
users clubs. Some of these clubs offer
free instruction to members, although
others charge a fee for instruction. This
seems like an ideal situation for adult
learners. Local experts can set up
classes for club members on topics of
interest. Club members determine the
areas of interest.
In order to institute this activity, a
fairly large club is necessary. The club
needs to be large enough to have more
than one expert in several areas. Also,
the club would need to have a fairly
large pool of members as students. This
activity offers benefits for the club, as
well as for members. The lure of free or
inexpensive adult education can help
boost membership.
Education is truly a lifelong activity.
No matter how much you know about
your computer, there is still more to
learn. With the possibilities available to
the adult learner, the limits of your
education are only what you decide to
place on yourself.

Keep track of those hard-won scores
Keeping Score With CoCo
'
By Lou Ashby
■ :
Until recently, the area around my
computer was a mess. Lots of
little bits of paper with cryptic
messages, such as "Bill Zaxxon 18000"
and "Luanne — Pacatak — 23,450,"
were scattered all over the place. They
represented (I discovered) landmarks of
achievement. Arcade gamesters are
proud of their high scores — and heaven
help anybody who misplaces one! My
three resident joystick jocks think their
game scores are even more important
than the latest issue of rainbow!
My solution to this problem is a
paper-eating program called CoCo
Scoreboard. I wrote it, put it on a disk
and stuck it in the box with the games
disks, and the clutter disappeared.
Neatness has returned and errant
breezes no longer threaten to disperse
the scores of my offspring.
The menu allows you to create the
games file, add games, insert or change
high scores, and display and print the
scoreboard, all from one LOAD or RUN.
Those with only I6K will have to delete
lines 10 through 90 and PCLEflR 1 to

avoid an OM Error in the game-add
function.
One advantage of direct file organi-
zation is that if a file doesn't exist, DOS
will build one, so you use the game-add
function to create your initial games
file. Just type in your game names in any
order (maximum length: 15 characters).
When you have entered them all, a final
ENTER will drop the program into a sort
to alphabetize the names and write the
records to disk. You also use this func-
tion whenever you add new games to
your collection. Your new additions will
be merged with the existing records and
sorted into their proper positions in the
file.
The second function allows you to
randomly insert or change player names
and scores on the game records. At the
"Game?" prompt, simply type in the
name of the game record you want to
update; if it exists, the system will find
it, display the current data and prompt
for changes.
If no update is to take place to a field,
press ENTER and the current data re-
mains. Otherwise, enter the player's
name (maximum: 10 letters), press
ENTER and type the score at the "Score"
prompt. One hint about the score field
— it is alphabetic. You can enter non-
numeric data (maximum: 10 charac-

ters), such as times, ratings or scores,
with punctuation for better visual im-
pact. Press Q to return to the menu.
The third function displays the score-
board sequentially on your monitor or
TV. This is an ego-builder for one and
all — see your name on the screen as
best-in-the-house at something.
To prevent excessive wear and tear
from looking up scores to see if a new
record has been achieved, use Function
4 to print an occasional list for quick
reference. This also helps minimize the
"oops" factor. Those without a printer
might want to keep the code for this
feature intact and simply change Line
150 from DN C GOTO 170, 280, 540,
790 to ON C GOTO 170 , 2B0 , 540 , 100,
which will reject entry into hard copy
logic until your printer arrives. (You will
get one sooner or later!)
Now if I can just design a program
that untangles joystick cables. □

Two Years In Ihe Making. Speech Systems
was formed to develop new and innova-
tive speech products. After 2 years of in-
tensive Research and Development, we
have created a truely sophisticated
speech recognition device. Recognition
rates from 95% to 98% are typical. Until
now, such a product was outside the
price range of Ihe personnel computer
market, and even small businesses.
EARS is trained by your voice and capable
of recognizing any word or phrase.
Training EARS to your particular voice
print takes seconds. Up to 64 voice prints
may be loaded into memory. You may
then save on tape or disk as many as you
like so that your total vocabulary is virtu-
ally infinite.
Speech and Sound Recognition. EARS is re-
ally a sound recognition system, so it re-
ally doesn't matter whether you speak in
English, Spanish, or French. In fact you do
not have to speak at all, you can train
EARS to understand sounds such as a
musical note or a door slamming.
Hands Off Programming. Imagine writing
your own BASIC programs without ever
touching the keyboard. Everything that
you would normally do through a
keyboard can now be done by just
speaking.
Programming EARS Is Easy. LISTEN,
MATCH and other commands have been
added to BASIC so that programming
EARS is a piece of cake! The single BASIC
line: 10 LISTEN: MATCH will instruct
EARS to listen to you and return the
matching phrase.
It Talks. EARS is also capable of high qual-
ity speech. We mean REALLY high quality.
The speech is a fixed vocabulary spoken
by a professional announcer. Speech
Systems is currently creating a library of
thousands of high quality words and
phrases. For a demonstration call (312)
879-6844, you won't believe your ears or
our EARS.
DISK OWNERS. EARS will work with any
disk system with either a MULTI-PAK or
Y-CABLE. Our new Triple Y-CABLE was
specifically developed for those wishing
to add SUPER VOICE as a third device.
You Get Everything You Need. You get ev-
erything you need including a specially
designed professional headset style noise
cancelling microphone. The manual is
easy to use and understand. Several
demonstration examples are included so
you don't have to write your own pro-
grams unless you want to. EARS will work
in any 32K or 64K Color Computer.
SUPER VOICE $20 OFF
Imagine talking to your computer and it
talking back to you. When you need an
unlimited vocabulary, you can't beat
SUPER VOICE. For a limited lime, we will
give you the SUPER VOICE for $59.95 with
your EARS purchase. Even if you already
have another speech unit, here is your
chance to buy the best and save $20.
VOICE CONTROL
Applications for EARS are astounding.
Here is our first of many listening pro-
grams to come. VOICE CONTROL is a
program specifically designed to allow
you to control any appliance in your
house with your voice and our HOME
COMMANDER (sold separately) or the
Radio Shack Plug 'N' Power controller.
For example, you can control your TV by
saying "TV ON" or "TV OFF". . $24.95

Put an end to alien-ation
Battle Back With Munchkin
Blaster
By Steve Donald
Aliens are attacking, zooming around the sky,
shooting laser bolts at your fuel tanks and crashing
"kamikaze" into your laser cannons. You're in
charge of defense at this military base, so it's up to you to
eliminate the aliens by aiming the cross hairs of your heavy
lasers and firing a bolt of energy at them.
To play Munchkin Blaster, push the firebutton to bring
up the game screen. In the bottom corners are your two laser
cannons, and in between them are your four white fuel
tanks, which must be protected at all costs. When either or
both of your lasers are destroyed, or all of your fuel tanks
are blown up, the game is over and you are asked, "Another
planet?"
After 20 aliens are eliminated, bonus points are awarded
for lasers and fuel tanks remaining. Then, a new set starts,
with all damages repaired and more vicious aliens to defeat.
I added the rapid fire feature to save your firing finger,
and you have the options of using the speed-up poke and
a high score. To make your high score permanent, change
Line 30 so that HS= your high score and H$= your name,
then resave the game. Good Luck!
(Questions about this game may be sent to Steve Donald,
Oba. Ontario, Canada POM 2P0. Please enclose an SASE
for a response.) □

rtificial intelligence is an area
i still in its infancy. If a computer
ican ever be designed that can

1 have written a short program, CoCo
I earn, that allows CoCo to learn to play
a game better. The first time 1 saw a
discussion of this game was about 10
years ago in <i maw ww~ —
'to reward the machine's moves every
time it wins and to penalize the moves
when it loses. This is accomplished by
labeling boxes with each possible move.
Thus, every game has to be designed
beforehand.
1 felt it would be better if the comput-
\ er's memory expanded as the difierent
.i 1 TUu tlnram" Cil U1C
ame moves in the same situation would
only be stored once.
Think how you learn to play a game.
At first, your moves arc only random.
But, after a while, you begin to find
certain methods that allow you to win
and others that cause you lo lose, litis
is what 1 wanted CoCo Learn to be able
to do. Each time a game is won, all
, moves in the game are rewarded with a
*, higher probability. If the game loses all
moves are given a lower probability.

58 THE RAINBOW August 1987
The scenario: You are flying your F-15 Eagle in
pursuit of an enemy fleet of craft intruding on your
airspace. Your orders are to shoot to kill.
F-15 Ground Assault Simulator is an action game
written specifically for the new Color Computer 3 with
128K. An RGB monitor is recommended for correct
color interpretation, but not needed.
You must perform your mission using the right joystick
and various keys on the keyboard to operate plane
functions.
After running the program, you are greeted by the title
screen and a short song. Next, you need to type the skill
level at which you want to play. The easiest is Level 0;
Level 9 is nearly impossible. Let's play Skill Level 3, just
for starters.
The game screen appears and you see a fuel gauge, a
horizon gauge, a thrust meter and radar (all of which
work in real time). Control your ship like a real aircraft:
to go up, pull the stick back and vice versa for down.
If you are not using an RGB monitor, you will not be
able to see your own aircraft. You will only see its shadow
on the ground. Therefore, pulling back and pushing
forward on the stick will have little visible effect.
The radar shows the enemy position in relation to the
screen, and the horizon gauge shows the ground in
relation to your craft. The fuel gauge shows how much
fuel is left in your tanks; when you run out of fuel, you
will crash. The thrust gauge controls the speed and
maneuvers of your plane. Use the up and down arrows
to control this factor. The more thrust you've got, the
more quickly fuel is used.
Move your ship into position and press the joystick
button to fire. Watch out: The enemy may shoot back.
The frequency of the enemy's attacks depends on the skill
level you picked at the start of the game.
Now that you know how to play, let's take a look at
how some of the game's effects are achieved. The moving
scenery is drawn in two palette colors. One is a visible
color and the other is the background color (invisible).
These colors are switched from visible to invisible, using
the palette command, at a speed that achieves

School. He is currently writing a line of computer
software that deals with games and utilities.
August 1987 THE RAINBOW 59
flicker-free animation. The variable for thrust controls how much
time passes before the next switch of scenery lines.
The game's graphics, like the plane's in-flight positions, are drawn
at the very beginning of the program right before the title screen
is displayed.
F-I5 Ground Assault Simulator uses the speed-up poke, G5497 , 0,
to make the program run even faster. It also uses the new Color
Computer 3's advanced graphics system and the 320-by-192, 16-
color screen. The palette colors for the screen may be changed to
fit your personal preferences; they are contained in Line 185.
1 hope this explanation will get you started, but if you have any
questions, please feel free to write.

COCO CONSULTATIONS
Technicians Tackle Shifty
Display
/ have a Co Co I and 2, two Co Co 3s,
three Zenith televisions, a CM-8 mon-
itor and some other brands of TVs.
When I hook either of the Co Co 3s to
the Zenith TVs, the picture jumps a
little. This does not happen when I hook
the Co Co 3 to either a CM-8 or another
brand of TV. Nor does it happen when
I hook the Co Co 1 or the Co Co 2 to the
Zenith TVs. Can you help me?
Wooten A. York
Lincolnton, GA
I have heard a dozen or so reports via
Delphi of problems with a jumpy pic-
ture with the CoCo 3. I'm still not really
sure what the problem is. However,
Tandy has noted a different, but per-
haps related, video problem with the
CoCo 3. It seems that on some CoCo
3s when you power them up, the 32-
column display either is missing or is
shifted over one or two horizontal
character spaces to the left and will
wrap around on the same line on the
right.
They discovered two possible causes:
In some cases, the GIME chip was
poorly seated in its socket, with some of
its pins making poor contact. In that
case, they advised their repair techni-
cians to remove the GIME chip (a very
delicate matter!) and clean both it and
Martin H. Goodman, M.D., a physi-
cian trained in anesthesiology, is a
longtime electronics tinkerer and out-
spoken commentator — sort of the
Howard Cosell of the CoCo world. On
Delphi. Marty is the SIGop of rain-
bow's CoCo SIG and database man-
ager of OS-9 Online. His non-computer
passions include running, mountaineer-
ing and outdoor photography. Marty
lives in San Pablo, California.

its socket with alcohol, then carefully
reinsert it.
They also noted that in some cases
there was a problem with a capacitor in
the clock circuit. In this case, they
advised their technicians to replace C-
64 (which is originally 150 picofarads)
with a 220-picofarad capacitor. I'm not
sure whether either of these manipula-
tions will help with your particular
problem, but you might want to try
them.
Pin Assignments
I have a book that describes the pin-
out of the CoCo's parallel port and lists
one of them as +12V and another as
-12 V. Does this mean that the book
only applies to the CoCo 1? What are
the pin assignments for the CoCo 2?
Where can I find books with specs on
the 7400 series of IC logic chips?
Steve Roy
Cincinnati, OH
The book you have is probably the
old, green "Technical Reference Man-
ual" for the ancient CoCo 1 'D' board.
What you are calling the "parallel port"
is more accurately termed the CoCo's
"system bus." As it happens, the pin
assignments for that system bus are
exactly the same on all models of CoCo,
with the one exception: Those two pins
you mentioned (the + and - 1 2-volt pins)
are, on the CoCo 2 and 3, not connected
to anything. Other than that, all pin
assignments are the same.
Actually, much of the CoCo's circuit-
ry has remained fundamentally the
same through all revisions of the ma-
chine. But to get an accurate reference
for your particular model CoCo, you
should order the service manual for that
particular model. The price will be
around $12. These service manuals tend
to be extremely well-written and very
educational.
As for the 74 series of logic chips.
National Semiconductor, Motorola
and Texas Instruments all publish
extensive reference books on these
items. Call your local representative for
any of these companies and find out
how to order one. They might give you
one free. These books are often on sale
at technical book stores, too.
Disk Access Problem
A friend complained to me of a Color
Computer that shows garbage on the
screen on the right-hand side during
disk access. It appears to work well
otherwise. Have you any idea how to
cure this?
Dave Archer
(DAVEARCHER)
In a Technical Bulletin to its repair
technicians, dated May 23, 1985, Tandy
discusses this problem. They say it can
be cured by soldering lOK-ohm, pull-up
resistors to the A0 and Al pins on the
main system bus of the CoCo. That is,
solder a 10K resistor between the pad

AINBOWfest is the only comput-
er show dedicated exclusively
to your Tandy Color Computer.
Nowhere else will you see as many CoCo-related
products or be able to attend free seminars con-
ducted by the top Color Computer experts. It's like
receiving the latest issue of the rainbow in your
mailbox!
RAINBOWfest is a great opportunity for com-
mercial programmers to show ott new and innova-
tive products lor the first time. Princeton is the
show to get information on capabilities for the
new CoCo 3, along with a terrific selection of the
latest CoCo 3 software. In exhibit after exhibit,
there will be demonstrations, opportunities to
experiment with software and hardware, and spe-
cial RAINBOWfest prices.
Set your own pace between visiting exhibits and
attending the valuable, free seminars on all as-
pects of your CoCo — from improving BASIC skills
to working with the sophisticated OS-9 operating
system.
Many people who write lor THE rainbow — as
well as those who are written about — are there to
meet you and answer questions. You'll also meet
lots of other people who share your interest in the
Color Computer. It's a person-to-person event and
a tremendous learning experience in a fun and re-
laxed atmosphere.'
To make it easier for you to participate, we
schedule RAINBOWfests in different parts of the
country. If you missed the fun in Chicago, why
don't you make plans now to join us in Princeton?
For members of the family who don't share your
affinity for CoCo, RAINBOWfest is located in an
area with many other attractions.
A special feature of RAINBOWfest Is the
Educational Sandbox, which features child-
oriented workshops to give hands-on experience
to an age group often neglected. There are ses-
sions for the kindergarten through third-graders,
and for fourth- through seventh-graders. And, as
an additional treat for CoCo Kids of all ages, we've
invited frisky feline CoCo Cat to join us for the
show. RAINBOWfest has something for everyone
in the family!
The Hyatt Regency Princeton offers special
rates for RAINBOWfest. The show opens Friday
evening with a session from 7 p.m. to 10 p.m. It's a
daytime show Saturday — the CoCo Community
Breakfast (separate tickets required) is at 8 a.m.,
then the exhibit hall opens promptly at 10 a.m. and
runs until 6 p.m. On Sunday, the exhibit hall opens
at 11 a.m. and closes at 4 p.m.
Tickets for RAINBOWfest may be obtained di-
rectly from THE RAINBOW. We'll also send you a
reservation form so you can get your special room
rate.

Seeking Schematics
/ have some Disio equipment and am
interested in getting the schematic
diagrams for it. These have not been
available in the past. Can you help me?
Dennis Skala
(DENNYSKALA)
Fairview, PA
1 am pleased to announce that CRC/
Disto has started providing schematic
diagrams for their products. Currently,
diagrams of their later revision RAM
disk card and their later revision Super
Disk Controller card are available.
Regrettably, the schematic they released
of the Super Disk Controller, while
showing the main disk controller
circuitry, still does not show the details
of the ROM select circuitry. Still, the
information they have released is a giant
step in the right direction.
Disto also has information available
on how to upgrade early model Super
Controllers to make them work with the
CoCo 3 (there were some problems with
some of these early models) and infor-
mation on how to upgrade the earliest
model RAM disk card to allow it to
function at 2 MHz, making it usable
with OS-9 Level II on the CoCo 3. Disto
will perform these upgrades for you for
a reasonable service and shipping fee, or
it will provide you with the information
you need to do it yourself. Both of these
sets of upgrade instructions are also
posted on Delphi in the CoCo SIG
Hardware Hacking topic area.
Six-Pin DIN
Where can I get a cable to hook my
new Magnavox Monitor 40 to my
CoCo 3's RGB port? This monitor has
a six-pin DIN socket for RGB input and
also features composite video input. I
can make one up myself if you tell me
how.
Jason McCampbell
St. Johns, MI
Your "Magnavox Monitor 40" is
probably the Magnavox 8CM505 mon-
itor, judging from your description of it.
This monitor (and also the Magnavox
8CM5I5 and 8CM643) all have the
same sort of six-pin DIN RGB input
jack. To make up a cable for it, you need
6 feel of 10-conductor ribbon cable, to
which you must crimp a 10-conductor
female dual in-line IDC connector, of
the sort that mates to the CoCo 3's RGB
connector. This connector is not avail-
able at Radio Shack, but can be ordered
from major electronic supply houses.
You also need a six-pin DIN connector,
available at Radio Shack.
Then, all you do is hook pins on the
Magnavox connector to pins with the
identical signal function on the CoCo
RGB connector:

CoCo RGB connector pins 6, 7 and 10
are not used in this cable arrangement.
You are quite lucky that the Mag-
navox takes separate and upgoing sync
for its RG B input — just the type of sync
the CoCo 3 provides! Note that some
other RGB monitors (like the Sony
KVI3IICR) require combined and
down-going sync, which in turn require
a sync combiner circuit in order to
accept the CoCo 3's RGB signals.
SAM Chip Assessment
In your February 1987 column, you
wrote that the 74LS785 is significantly
better than the old 6883 SAM chip. Is
this chip pin-compatible with the older
Co Cos? Where can I get one? My store
manager here in Canada refuses to help
me acquire one.
Also, I just discovered that the F. N
and V keys won't work on my CoCo.
My G and SHIFT keys have just died,
too. When I try my keyboard on my
friend's CoCo, it works fine, but his fails
in the same way on my CoCo. I noticed
that my 6821 (1117 on my CoCo 'F'
board) is running hot too. Is this the
problem? Where can I get a new 6821?
Steven Stady
Colinton, Alberta
If your CoCo is working fine, there
is no reason to replace the SAM chip.
The 74LS785 is indeed totally pin-
compatible with the older 6883 chip
(also known as 74LS783) and can
simply be dropped into older CoCos,
where it will work just fine. If you were
having problems with your old SAM,
however, it is possible that this new one,
which has somewhat refined internal
timing, may work better. It also may run
cooler and last longer.
The part number for the 74LS785
chip is MX-6433. When ordering it, say
you want "a 74LS785, Part Number
MX-6433, for a CoCo Catalog No.
263134A." In the U.S., Radio Shack
stores can order parts directly from
National Parts. You may have to call
Fort Worth and order the part yourself.
As to your second problem, UI7 has
nothing to do with reading the key-
board, which is governed by UI8, the
6822 chip. But U17 (the 6821) should
not be running hot to the touch, and so
it may need replacement. Before you
run around replacing chips without
knowing what you are doing, I strongly
urge you to get a service manual for
your particular model CoCo. If you
don't have a schematic and technical
reference for your machine, you really
should not be attempting any repairs.
The F,V, period and N keys (along
with the right arrow and 6 key) are all
in the same column of the keyboard
scan, hooked to Wire Number 15 of the
keyboard connector. The G and shift
keys (along with the O, W, space, 7 and
slash key) are in the column hooked to
keyboard Line Number 16. Thus, I
suspect that either at least two lines are
out on your motherboard, or your U 18
6822 is on the fritz.
All CoCo parts can be ordered from
Tandy National Parts. The 6821 chip is
a standard chip available from dozens
of electronic parts suppliers. The Tandy
National Parts number for the 682 1 chip
in my CoCo 1 'F' board service manual
is 8040821, and for the 6822 chip is
8040822. The 'F' board is catalog
number 26-3004A.

COMMENTARY
A Guide to RGB Analog
Monitors for the CoCo 3
By Marty Goodman
Rainbow Contributing Editor
The term "RGB monitor" refers to
those color monitors that accept
luminance information for red,
green and blue intensities on three
separate wires. All such monitors must
also be given synchronization ("sync")
information. This is accomplished by
providing sync pulses either combined
with the green luminance line, on a
single separate wire (Sony), or via two
separate wires.
Other things that can vary on RGB
monitors are whether the luminance
information is sent in analog or digital
fashion, the exact details of the timing
of the sync information, the voltage
levels the monitor wants to see on the
R, G and B lines, and the horizontal
scan rate of the monitor. 1 want to make
it clear that there is no such thing as a
standard RGB monitor.
Analog Versus Digital
One of the major divisions among the
many sorts of RGB monitors is between
"analog" and "digital" (sometimes also
called TTL, RGB I or RGB X) RGB
monitors. The Color Computer 3 must
have an analog RGB monitor in order
Martin H. Goodman, M.D., is a long-
lime electronics tinkerer and lives in
San Pablo, California. Marty is a RAIN-
BOW contributing editor and writes the

S/G and database manager of OS-9
Online on Delphi.
68 THE RAINBOW August 1987
to resolve its full palette of 64 colors.
Most inexpensive RGB monitors on the
market today are digital RGB monitors,
and cannot be used to display more than
eight colors with the CoCo 3, and even
for that it takes a special hardware
adapter (currently made and sold by
J&M Systems). The reason digital RGB
monitors are so prevalent is that the two
most common RGB protocols used
with IBM PCs and clones are digital in
nature. These are the Color Graphics
Adapter standard (CGA RGB I) and
Enhanced Graphics Adapter (EGA
RGB). The T refers to the presence of
a separate intensity line in the signal
protocol.
On agiven line, digital RGB monitors
can recognize only an "on" or "off"
condition. Thus, on the CGA protocol,
the R, G and B intensity at a given point
can be only either on or off. This yields
capability to display a total of eight
different colors. By adding an I line that
can exist in either of two states (on or
off) the IBM CGA standard is able to
double this and display a total of 16
different colors. The IBM EGA stand-
ard adds an extra R, G and B line and
so allows for 8 by 8 or 64 possible color
combinations. IBM EGA standard also
involves a faster horizontal scan rate,
allowing for greater vertical resolution.
Analog RGB monitors do not need or
use intensity lines. Instead, intensity
information is conveyed by the exact
voltage on each of the red, green and
blue lines. This voltage may vary con-
tinuously, and, in theory, an RGB
analog monitor can express 16 million
or more different colors. In practice, the
number of different colors an RGB A
monitor can resolve will be limited by
how finely the computer driving it is
capable of varying the R, G and B signal
levels. In the Color Computer 3, the
GIME chip reserves a total of two bits
per luminance line for specifying vol-
tage and thus can set the R, G and B
lines to one of four different voltage
levels, allowing for 4 by 4 by 4 or 64
different total colors in its palette. By
comparison, the Atari 520 and 1040 ST
systems allow for three bits of voltage
level data on each of the luminance
lines. They can set the R, G and B lines
to any one of eight voltage levels and so
can resolve a total of 512 different
colors in the palette. The Amiga, allow-
ing four bits per luminance line, has
provisions for any of 16 different vol-
tage levels on its R, G and B lines,
resulting in a total of 4,096 colors in its
palette. The IBM "PGA" standard (a
seldom-used analog RGB protocol used
on some IBM systems) also can resolve
a total of 4,096 colors.
Analog RGB protocol is used for
professional video signal transmission.
This is because its analog nature allows
expression of the full range of possible
colors. Its separate transmission of
RGB and sync information allows for
much greater image resolution than
does the "mushy" composite color video
protocol commonly used on most home
video equipment. In composite color
video, all of the color and sync informa-
tion is mashed into a single wire. The
result is reduced signal quality.

Monochrome as an Option
Note that it is the mashing of all the
color information into a single wire that
causes the degradation of signal quality.
Composite monochrome signals are
usually of quite fine resolution. Color
picture tubes of fine-resolution phos-
phor are difficult and expensive to
produce. This is due to the need to lay
down extremely tiny dots or stripes of
red, green and blue phosphor, fabricate
and precisely position inside the tube a
"shadow mask" to allow the electron
beam to individually light up each
cluster of red, green and blue phos-
phors. In a monochrome monitor, a
single phosphor is "smeared" continu-
ously across the surface of the tube, and
there is no need for a shadow mask. All
of this makes a color monitor with
resolution equivalent to a monochrome
monitor cost six to 10 times as much.
If all you want is to resolve 80-column
text, then perhaps you don't need an
RGB monitor at all, but rather a com-
posite monochrome monitor. Tandy
sells one such (the VM-4), and so do
Computerware, Howard Medical and
other RAINBOW advertisers. Tandy's
VM-4 is perfectly compatible with the
CoCo 3 and will sharply resolve 80-
column text. Indeed, the 80-column text
you get with the $115 VM-4 is some-
what sharper than that which you
would get using a $600 NEC Multisync
RGB monitor.
What Monitors Work With a CoCo 3?
When looking for an RGB monitor
for the CoCo 3, you need to get an
analog RGB monitor. Most monitors
advertised as "digital," "TTL," "IBM-
compatible," or "RGB I" will not work
with a CoCo 3. However, a few mon-
itors have been designed to provide a
variety of different inputs, including
RGB 1, RGB A and, in some cases,
composite video. These monitors are
most desirable to CoCo 3 owners. Such
monitors will work fine with an IBM
PC or Tandy 1000 or similar clone, and
will work fine with a CoCo 3. Monitors
that also have a composite video input
will allow CoCo 3 owners to view the
vast number of CoCo games and edu-
cational software written over the last
five years using "artifact colors." Any
attempt to display such "artifact colors"
on an RGB A-only monitor will result
in the screen appearing in black and
white.
Shopping for an RGB A Monitor
for Your CoCo 3
As I have noted in some "CoCo
Consultation" columns, there are many
factors that make up a good RGB
monitor. Some are product specifica-
tions and others are seldom measured
or listed. But the bottom line is that no
combination of product specs will tell
you exactly which RGB A monitor is
better than another. You must look at
the image made by the CoCo 3 on all
monitors and compare. This is difficult
"If all you want is to
resolve 80-column
text, then perhaps
you don't need an
RGB monitor at all,
but rather a compos-
ite monochrome
monitor. "
because the different RGB A monitors
are never sold in the same stores and
often are hard to find, or they are
available only by mail order. It is even
more difficult because for each different
monitor, a special RGB A cable usually
has to be made up. Over the last three
months, I have viewed the CoCo 3's
output on six different RGB A
monitors.
Probably the most relevant of the
commonly listed specifications for RGB
monitors is the "stripe width" (or, for
those monitors whose phosphor is laid
down as dots, the "dot diameter" or
"dot pitch"). Ed Ellers, RAINBOW Con-
sulting Editor, tells me that .50mm
stripe width is often considered, by rule
of thumb, the absolute minimum
needed for proper resolution of 80-
column text. The monitors I discuss
below feature stripe widths ranging
from .65mm to .25mm. Note that unless
we are talking about monitors that all
have the same size tube, the stripe-width
figures have to be "normalized" to the
tube size in order to provide a meaning-
ful comparison of the resolution of the
system. That is, a 26-inch diagonal
monitor with a stripe width of .74 will
be able to resolve exactly the same
sharpness of image as a 13-inch diago-
nal monitor with a stripe width of
.37mm. Obviously, the issue here is the
total number of stripes per horizontal
line. The monitors we compare are all
in the 12- to 14-inch diagonal measure
range. I judge this range to be suffi-
ciently narrow, so I will not attempt to
"normalize" the stripe widths to tube
size.
Tandy CM-8
This is the monitor Radio Shack
specifically designed to work with the
Color Computer 3. It has a phosphor
rated at .52mm stripe width and provi-
sions for only CoCo 3 type analog
inputs. The diagonal tube measure is 13
inches. It will not work with any other
type of computer, nor will it work with
a VCR. It cannot display artifact colors
because it lacks a composite video
input. The resolution of 80-column text
is adequate, but not strikingly crisp. Its
screen image is somewhat dimmer than
that of the other RGB monitors dis-
cussed in this group. In addition, many
owners have complained that the cable
provided is a tad short. On the positive
side, it is (at the $250 mail order price)
by far the least expensive RGB A mon-
itor available that will work with the
CoCo 3. Should it develop problems, it
can be serviced via any Radio Shack
store. Spectrum Projects sells an RGB
video extender cable that can add about
6 feet to the length of the CM-8's (or any
other CoCo RGB monitor's) cable,
without substantial loss of signal qual-
ity. The CM-8 is by far the easiest CoCo
3 RGB A monitor to find. Because of
its availability and low price, the CM-
8 from Tandy is likely to be the most
popular CoCo 3 RGB monitor.
The Magnavox "Professional"
8CM515 Monitor
This was the first CoCo 3 RGB A
monitor I owned, and it is the one
currently used by Steve Bjork, Richard
Esposito ("Doctor ASCII") and Paul
Searby (founder of Computerware). It
has a rated stripe width of .42mm and
a tube measure of 13 inches diagonally.
It features provisions for RGB I, RGB
X, RGB A and composite video inputs
and boasts a frosted anti-glare screen.
It also has audio inputs and a switchable
comb filter. It will work with IBM PCs
(CGA RGB I protocol), CoCo 3s (RGB
A), CoCo 2s and VCRs (composite
color video) and can resolve artifact
colors on the CoCo 3. You can switch
between RGB A and composite video
inputs via a convenient push button on
the front panel of this monitor. It
resolves 80-column text a bit more
sharply than does the CM-8 from

Tandy, and its screen image is some-
what brighter, as well. Its styling is
compatible with the rest of the Color
Computer system. The specific type of
RGB A protocol that Magnavox uses is
exactly the same as that of the Color
Computer 3. Both use separate and up-
going H and V sync lines. Making a
cable to hook the CoCo 3 to the Mag-
navox is easy. Merely obtain the ap-
propriate 10-pin CoCo RGB A type
connector and 6-pin DIN connector
used on the Magnavox (the same as that
used on the newer Tandy two-button
joysticks) and, referring to the user
manuals for the CoCo 3 and the Mag-
navox, merely hook R to R. G to G, B
to B, H sync to H sync, V sync to V sync,
and ground to ground. Sound is sup-
plied via a separate phono connector
that can hook to the CoCo 3's separate
audio output.
As you can probably tell, 1 am im-
pressed with the Magnavox 8CM515
monitor. But it does have some flaws.
Its handling of composite video input is
less than excellent. When used in com-
posite video mode, some 8CM5I5s
occasionally fail to pick up the color
burst signal from the CoCo, resulting in
a black and white image. A few of the
Magnavox 8CM515 monitors I've
tested have trouble accepting the verti-
cal sync pulse from the CoCo 3, al-
though in some cases, analysis indicated
that the CoCo 3 in question had a
marginal 74LS04 buffer chip, which
needed to be replaced. Finally, while the
video is a bit sharper than that of the
Tandy CM-8, there still is some appreci-
able blurriness in the 80-column display.
Not a whole lot, but some.
The Magnavox 8CM515 is approxi-
mately $100 more than a Tandy CM-8.
It is currently being offered by Spec-
trum Projects and Howard Medical
[See review on Page 140]. Both of these
are RAINBOW advertisers. Spectrum
Projects and SpectroSystems (of ADOS
fame) also sell, separately, cables that
can be used to hook the CoCo 3 to the
Magnavox series of monitors. As I
designed and, in most cases built, those
cables, it would not be fair for me to
review them. For the average CoCo 3
owner, when all is said and done, a
Magnavox 8CM515 will end up costing
about $330 to $350. In my opinion, the
added cost is well worth the added
quality and capability it yields, but the
individual user and his pocketbook will
have to be the final judge.
The Sony KV-1311CR
This has virtually all of the features
of the Magnavox monitor (except for
support for Apple's RGB X protocol),
but features a somewhat brighter and
sharper phosphor(.37mm stripe width).
It also is a full-function, infrared remote
control, 13-inch diagonal measure tele-
vision! It has somewhat better quality
circuitry for its color composite video
input than does the Magnavox
8CM515.
This is the monitor that Bob Rosen,
of Spectrum Projects, and I currently
use on our CoCo 3s. When used with
80-column text, the image is very sharp
with only a trace of fuzziness to the
letters. When used to display CoCo 3
graphics, the images are extremely
sharp and the colors quite vibrant.
When used as a color TV, it produces
a stunningly sharp picture, so much so
that quite a few of my friends have,
without prompting, remarked on its
fine picture quality. There is one quirky
trick to using the audio input on the
Sony KV-131 1CR: To use the separate
phono jack audio input with the analog
RGB input, you must simultaneously
push down both the RGB and "Video"
(composite color video) selector but-

tons on the front panel so that they both
lock in the ON position. Only then will
you get RGB A video input and be able
to pipe in sound through the RCA
audio input jack on the side of the
monitor.
Howard Medical Computers now
offers the KV-131 ICR for S449 (plus
S15 S/H) and has the necessary cable
for S36. Spectrum Projects also carries
the cable to hook up a CoCo 3 ($40).
The cables are complex and, therefore,
expensive. Overall, I am very pleased
with my Sony KV-1311CR.
Note: In a "CoCo Consultations"
column I incorrectly stated that the
Sony KV-1311CR had been discon-
tinued. This was my mistake.
Hackers Note Regarding
the Sony KV-1311CR
The Sony KV-1311CR uses a rather
odd 34-pin RGB A connector, and its
provisions for RGB A input are for a
slightly different protocol than that
used by the CoCo 3. The Sony wants to
see a combined and down-going sync
signal, whereas the CoCo produces
separate and up-going sync signals. In
order to hook it to the CoCo 3, you have
to combine and then invert the sync
lines from the CoCo 3. A single NOR
gate on a 74ALS02 chip does this quite
nicely. A second problem faced by
would-be cable makers for the Sony
KV-1311CR is that you need a source
of +5 volts to power the 74ALS02 chip.
The Sony does not supply this, and it
is not present on the CoCo 3 RGB A
connector either. Using a "sneaky trick"
in commercial Sony RGB A to CoCo
3 cables that I designed for Spectrum
Projects, I "stole" a source of +5 volts
from one of the joystick connectors on
the CoCo 3. Although note, on my own
Sony, I opened the monitor and
brought a source of +5 volts out to two
of the unused pins on its 34-pin connec-
tor (pins 1 and 2). This enabled me to
make a cable that did not have to take
up one of the joystick ports. Regulated
+5 volts is available on either Pin 14 of
the 14-pin IC or Pin 16 of the 16-pin IC
that is near the 34-pin RGB A connector
on the vertical PC board inside the
Sony.
Magnavox 8CM505
Despite the similarity of its model
number to the Magnavox "Profes-
sional" 8CM515, the Magnavox
8CM505 is a less desirable beast. Its
stripe width is only .65mm and cannot
adequately resolve 80-column text. It is
a possible choice for those who want to
use the CoCo 3 for dedicated color
graphics systems, for it will quite ade-
quately resolve 320-by-200 pixel resolu-
tion graphics. Like the 8CM5I5, it
features RGB A, RGB 1 and composite
video inputs. In my area. Toys R Us
sells this monitor for $200 plus tax. It
can be hooked to the CoCo with the
same cable used for the Magnavox
8CM5I5.
Magnavox 8CM643
If you run across a Magnavox
8CM643 monitor at a reasonable price,
it might be a good choice for the CoCo
3. It is very similar to the 8CM515
except that it has a somewhat better
quality picture tube that boasts a stripe
width of .39mm (compared to the
.42mm stripe width of the 8CM515).
NEC MultiSync
This monitor costs approximately
$580 and is primarily of interest to IBM
PC users who want support for high-
quality EGA and PGA video screens. It
is a very popular ultra-high-quality
IBM video monitor, so RAINBOW read-
ers encountering it may want to put it
to use on their CoCo 3s. The NEC
MultiSync boasts a dot width of .31mm.
A 14-inch diagonal screen accepts
analog RGB input. It also accepts IBM
CGA, IBM EGA and IBM PGA inputs,
although it does not have provisions for
composite video input. Making a cable
for it is easy. It uses standard DB 9
connectors and calls for the same up-
going and separate sync arrangement as
that used by the CoCo 3 in analog RGB
mode. Its image is superbly crisp and
sharp. Spectrum Projects sells CoCo 3
to NEC MultiSync cables, designed and
manufactured by yours truly.
Sony CDP-1302 (Multiscan)
This is the finest quality monitor you
can buy for under $1,000. Retailing for
$800, it boasts a stripe width of.25mm,
and its "multiscan" feature, like that of
the NEC MultiSync, allows it to be used
with the high resolution IBM EGA and
PGA protocols as well as with the lower
resolution IBM CGA and CoCo 3
RGB A type of video signals. Unfortu-
nately, it lacks composite video inputs,
so it cannot be used with the CoCo 2
or 3 to display artifact colors. As is the
case with the NEC MultiSync, this
monitor represents "overkill" when
used with a CoCo 3. Unlike the NEC
MultiSync, construction of a proper
cable to hook it to the CoCo 3 is a little
tricky, for the same reasons that hook-
ing the Sony KV-131 1CR to the CoCo
3 is tricky: its preference for combined
and down-going sync pulses.
Teknika MJ305
This monitor offers support for both
RGB A (CoCo 3 compatible) and RGB
I (IBM CGA compatible) video signals.
I saw it used with a CoCo 3 in a booth
at Color Expo '87. It has a rated stripe
width of .4 lmm and a diagonal measure
of 14 inches. Its image has about the
same quality as the Magnavox Profes-
sional 8CM515. Unfortunately, it costs
a bit more than the Magnavox 8CM5 1 5
and does not have provisions for com-
posite video input. Therefore, unless
you get a good deal on it, I cannot
recommend it.
Sony CDP-1310
This 13-inch diagonal measure,
.37mm stripe width monitor offers the
same fine display in Analog RGB video
mode as does the Sony KV-131 1CR.
However, although it supports RGB I
for the IBM CGA, it does not have
provisions for composite video input.
Thus, it lacks flexibility. Like the KV-
131 ICR, it is a little tricky to interface
to the CoCo 3. Unlike the KV-131 ICR,
it uses a rectangular 8-pin RGB video
connector.
Sony CDP-9000 and CDP-1201
These monitors are, respectively, 9
and 12 inches in diagonal screen mea-
sure. Both boast a super fine stripe pitch
of .25mm, making them possessors of
the finest resolution phosphors among
these monitors discussed. Note that the
CDP-9000, with only a 9-inch diagonal
measure tube, offers roughly the same
resolution as the KV-131 ICR with its
13-inch tube and .37mm stripe width
phosphor.
Both of these support only RGB A
and CGA RGB I type inputs and do not
provide for composite video. Like the
CDP-1310, they use an 8-pin RGB
connector and require combining and
inverting of the CoCo 3's sync lines in
order to work.
I've seen the CDP-9000 selling for as
little as $250. At that price, if you are
a hacker capable of making up a proper
cable for it, it represents a better value
than the CM-8 from Tandy, with a
smaller screen size, of course.
The CDP-1201 is rather overpriced
($500) and under-featured (it lacks
MultiSync capability), so unless you
already own one or can get a real deal
on one, I would not recommend it.
Sony KX-1211HG ("Profeel") Monitor
This is a 12-inch diagonal RGB mon-
itor with similar properties to that of the
KV-131 ICR. It is an older unit and
offers a slightly less fine stripe width on
74
THE RAINBOW August 1987
its phosphor. It still produces a good
quality image. It has all the flexibility
of input as the KV-13I1CR (RGB I,
RGB A, and composite video). It also
features a more complex implementa-
tion of the Sony 34-pin RGB A "stand-
ard" connector, which includes support
for stereo audio and, of greater interest
to CoCo 3 owners, supplies regulated +5
volts on pins 1 and 2 of that connector.
Thus, it is possible to make a "cleaner"
RGB A CoCo 3 cable for an unmodified
KX- 1 2 1 1 HG. I've made two such cables
for friends with this model of TV/
monitor, and both are quite pleased
with the images that resulted.
Sony KV-20XBR, KV-25XBR, KV-
2011CR, KV-2511CR
These are 20- and 25-inch diagonal
RGB monitors/TV sets. The 20-inch
models offer .37mm stripe width, and
the 25-inch models offer .55mm stripe
width (the latter combination should be
equivalent to a 13-inch monitor with a
.29mm stripe width). I have not inter-
faced any to a CoCo 3, but suspect the
process would be similar to that of
hookingaKV-BUCRtoit.
Miscellaneous Monitors
Beware of the Magnavox 8CM562
monitor! This monitor does not support
RGB A and is of no use to CoCo 3
owners. Thomson is putting out a line
of RGB monitors, but my preliminary
assessment of that line is that it is
overpriced and under-featured. Some
don't have RGB A input and, of those
that do, some lack composite video
input. Their stripe widths are not that
impressive. The Atari ST RGB Color
monitor would seem to be a possibility
for use with the CoCo 3. Superficially,
all of its relevant video signals match
those of the CoCo 3's output. But Atari
slipped a joker into the deck by imple-
menting an odd variant of sync timing.
If you try to put up a CoCo 3 image on
an Atari RGB monitor, the picture is
shifted up and to the right to an extent
that it cannot be compensated for with
the external horizontal and vertical
position adjustments. A video hacker
could probably fix this. The Amiga
model 1080 monitor might be usable
with the CoCo 3, but, in RGB analog
mode, it wants a combined down-going
horizontal and vertical sync. I'd be
interested to know if readers have
gotten the Amiga monitor to work on
a CoCo 3. The approach should not be
more tricky than that which I used with
the Sony KV-I3 1 1 CR, unless the Amiga
design has surprises similar to those in
the Atari.
Conclusions and Recommendations
The information here will better
enable you to make the best possible
choice of RGB A monitor for your
CoCo 3. Hopefully, if you encounter a
monitor other than those described
here, this article will have armed you
with the knowledge needed to assess
whether it is likely to work with a CoCo
3 and how good a value it represents.
There are three monitors I particu-
larly recommend. The CM-8 from
Tandy, though lacking in flexibility and
image quality, represents the least
expensive and most accessible CoCo 3
monitor. It's the easiest to have re-
paired.
The Magnavox 8CM515 represents
the best compromise monitor 1 know of.
Although priced a hundred dollars
higher than the CM-8 from Tandy, it
offers belter quality and much greater
flexibility of video input modes.
For those who want a little better
quality, or who want the option of using
their monitor as a TV at times, and who
can afford to spend another S50 to S 1 00,
the Sony KV-131 1CR would be the best
bet. /R\

RAINBOW
Give us your best: Join the ranks of these courageous CoCoists in showing the Color Computer world your
high score at your favorite micro-diversion. We want to put your best effort on record in THE RAINBOW'S
"Scoreboard" column. All entries must be received 60 days prior to publication. Entries should be printed —
legibly — and must include your full name, address, game title, company name and, of course, your high score.
Each individual is limited to three score entries per month. Send your entries to Scoreboard, c/o THE RAINBOW.
The "Rainbow Scoreboard" is now a bimonthly feature.
For greater convenience, your high scores may also be sent to us through the MAIL section of our Delphi
CoCo SIC From the CoCo SIG> prompt, pick MAIL, then type SEND and address to: EDITORS.

In conjunction with the rainbow's Scoreboard, which appears
bimonthly, we offer this column of pointers for our game-playing
readers' benefit. If you have some interesting hints, tips or responses
to questions, or want help yourself, we encourage you to write to the
.Scoreboard, c/o the rainbow.
FEEDBACK
In response to letters from:
• Travis Stromer: In Raaku-Tu, go to
the gargoyle's room, light the candle and
leave. Go to a room or two and wait for
a while, then go back to the gargoyle's
room and extinguish the candle.
• Jason Thomas Wysokowski: To open
the safe in Vortex Factor, go back in time
to the old museum and go to the room
with the desk. Open the desk and read the
document inside.
Tony Warchules
Nanticoke, PA
• Jason Jones: In Bedlam, you cannot
August 1987 THE RAINBOW 79
••••••••••••••••••••••••••••••••••••^
open the cabinet. You must gel the key
in the hole with the window hook in order
to open the red doors.
• Frank Morrison: In Pyramid 2000, you
must drop the scepter and get the bird.
You must have the box, though. When
you get to the pharaoh's room, type
THROW BIRD.
• Bill Hoban: In Shenanigans, you must

By Bill Bernico
and George Aftamonow
The following program is a Lo-Res text screen version of
the ever popular card game, blackjack. The object is to beat
the dealer's hand by getting as close to 21 points as possible
without going over.
After the cards are dealt, you will be given the opportunity
to take additional cards. If you feel your hand is good enough,
answer no to the prompt. The computer will then deal itself
a hand, trying to beat yours.
You start the game with SI 00 and can bet any or all of it
at a time. The game ends when the money is gone.

With summer's warmth and sun come an array of outdoor
extravaganzas — picnics, fairs and sporting events. Catch the
excitement of this last example with Speedster, an Indiana-
polis 500-type race car game.
You take control of a high-speed race car and must stay
on the dangerously winding road as long as possible. A crash
ends the game and displays the total score on the screen.

TEXTPRO III is an advanced word processing system designed for
speed, flexability and exlensive document processing. It is not like
mosl of the other word processing programs available for the Color
Computer. If you are looking for a simple word processor to write
letters or other short documents, then most likely you'll be better
off with one of the other simpler word processors. But. if you want
a powerful word processor with exlensive document formatting
features to handle large documents, term papers, manuals, complex
formating problems and letter writing, then TEXTPRO III is what
your looking for. TEXTPRO works in a totally different way than
most word processing programs. It uses simple 2 character
abbreviations of words or phrases for commands and formatting
information that you imbed directly in your text. There are over
50 different formating commands you can use without ever leaving
the text your working on. There are no lime comsuming, and oflen
furstraling menu chases, you are in total control at all limes. The
formatted oulpul can be displayed directly on Ihe screen, showing
you exactly whal your printed document will look like before a
single word is ever printed. This includes margins, headers,
footers, page numbers, page breaks, underlining, column formating
and full justification.

display. Plus you can select any foreground and backbround colors
or even color or monochrome display modes. It even supports 512K
by adding an aulomalic 2 drive Ultra Fast RAMDISK for lightning
fast assembly of program source code larger than memory. The

HI-RES III was designed lo improve the standard display capabilities
of Ihe Color Computer 3, even the 40 and 80 column displays have
several features missing. For example you can'l use PRINT O or
have different character sizes on the same screen, even mixing
text and graphics with the HPRINT command leaves a lol to be
desired. HI-RES III can give you the kind of display capabilities you
always dreamed about having on your color computer bul didn't gel
wilh your COCO-3. Well now it's here and wilh a wide varieLy of
display options that you can easily use wilh your Basic or ML
programs. HI-RES III is totally compatible with Enhanced Color
Basic and its operation is invisible lo Basic. It simply replaces the
normal screen display with an extremely versatile display package.
It also overcomes some of the disadvantages found when using the
Width 40 8. 80 screens. You can use the Print © function on any
line length wilh HI-RES III. II also gives you a programmable
automatic key repeal that can be very handy for ediling your Basic
programs. Automatic key repeat can be adjusted from ultra fast to
super slow and can be disabled entirely if desired. You also get a
full control code keyboard using the 'CTRL' key. So many of HI-RES
Ill's extended functions can be controlled directly from the keyboard
easily. With just a couple of simple keystrokes you can change
character sizes and styles at any time. You can even switch back
ond forth bolwoon tho standard COCO-3 display and HI-RES III wilh a
simple keyboard entry or under program control. But. after you
use HI-RES III. you most likely won't want to do without it again.
HI-RES III can be used for a wide variety of applications, wilh its
many different character sizes and styles. You can make your
program really look professional, wiui protected menus. Dold or
Italic emphasis. Double or Quad characters for easy to read displays
& menus. II can be idealy suited for Video Titles or Store Displays.
Printing Signs or Fliers in conjunction wilh a Hi-res Screen dump
program. The visually impared will espically appreciate the extra
large character sizes available.

When magicians take the stage, eyes fill with awe as
unlikelihoods become realities, over and over again. Now you
can play with a magic puzzle that has intrigued mathema-
ticians and magicians alike for centuries — the magic square.
This program, Magic Square, produces a 16-block square.
When a number between 35 and 70 is entered, a square of
different numbers (four columns and four rows) is displayed.
The sum of these numbers (added vertically, horizontally and
88 THE RAINBOW August 1987
diagonally) is the original number you entered. Additionally,
the four corner numbers add up to your original number.
Since magicians do not disclose how their tricks work, the
secret to how this program accomplishes its magical display
is not revealed. However, since you will be entering the
program into the CoCo, you will be, in effect, behind the
scene and can figure out the magic of how the program works.
Remember: A good magician never gives away the secret.

The following program is a simple version of the popular
Hangman game. The object is to guess random words in six
tries.
If the letter you choose is in the word, the computer shows
you its position in the word. Play continues until you guess
all the letters or make six mistakes.
If you want to add your own words, change the DATA
statements in lines 600 and 610 or add more lines. Afterward,
count the number of words and make the change in Line 10.
(The last number in the parentheses should become the
number of words in your DATA statements.)

Scrambled letters fill the screen. A timer, set at 90 seconds,
begins its countdown. You must find and write down as many
words as possible before the timer beeps at zero.
You can use any combination of letters going in any
direction (up, down, right, left, diagonal, forward or
backward) as long as the letters are adjacent. As an example,
you can form a word by going up two letters, diagonally three
letters, and then left two letters.
Grab a piece of paper and a bunch of friends, have a seat
in front of your CoCo, and give this program a try!

descriptions into the boxed areas. This makes the map much
more readable.
The Adventurer's job of mapping just became quite a bit
easier!

oy or oysticks
By Richard S. Ellis
Do you ever wonder if your joystick is working properly?
Lots of people do, and, unfortunately, they're either still
wondering or they've gone out and bought a new one.
Joystick Check-Out does just what its name implies, The
program provides information on the position of the left and
right joysticks and firebuttons simultaneously. It also
explains how joystick routines work.
Simply plug in your joysticks, run the program and read
the data. Refer to Figure 1 to determine if the joysticks are
working properly.
The program is short, but informative — perfect for
inquisitive minds.

Contributions to "Novices Niche" are welcome from everyone. We
like to run a variety of short programs that can be typed in at one sitting
and are useful, educational and fun. Keep in mind, although the short
programs are limited in scope, many novice programmers find it
enjoyable and quite educational to improve the software written by
others.
Program submissions must be on tape or disk. We're sorry, but wc
cannot key in program listings. All programs should be supported by
some editorial commentary, explaining how the program works. If your
submission is accepted for publication, the payment rate will be
established and agreed upon prior to publication.

Like ducks to water,
kids really take to
The Spelling Game
By Fred B. Scerbo
Rainbow Contributing Editor
Editor's Note: If you have an idea for
the "Wishing Well." submit it to Fred
c/o THE RAINBOW. Remember, keep
your ideas specific, and don 7 forget that
this is BASIC. All programs resulting
from your wishes are for your use. but
remain the property of the author.
Last month I introduced a pro-
gram titled CoCo Keys, which
could be used to introduce
youngsters to the workings of a comput-
er keyboard. By now, most of you have
typed in that program or loaded it from
your rainbow ON TAPE or DISK. Since
it is still too early to tell whether or not
any of you liked the program, I can only
hope that your reactions are similar to
those of the people I let try the program
prior to its publication. Their verdict
was thumbs up!
That program, if you recall, was
based on a suggestion from Sonya
Hurst of Richmond, California. She
was trying to design a keyboard pro-
gram that could be used for spelling
with her 5-year-old daughter. The pro-
gram would work with Radio Shack's
Speech/ Sound Cartridge. As of this
writing, 1 do not know if she succeeded
Fred Scerbo is a special needs instructor
for the North Adams Public Schools in
North Adams, Massachusetts. He holds
a master's in education and has pub-
lished some of the first software avail-
able for the Color Computer through
his software firm, Illustrated Memory
Banks.
in creating her own program. CoCo
Keys was not exactly what she re-
quested, but it was a start for the major
working parts.
Therefore, this month, CoCo Keys 2
will completely grant that wish by
providing a spelling program with a
graphics keyboard and speech thrown
in as an added bonus. What is really nice
about this program, however, is that it
can also be used as a game without the
Speech Pak as a way of reinforcing
spelling skills with keyboard locations.
Putting the Finishing Touch
I really thought I had the system beat
this time by getting the program written
a few weeks ahead of schedule. Only a
little work was needed to transform
CoCo Keys to CoCo Keys 2. Most of
the hard parts, such as the graphics
keyboard, were already designed. What
1 did not expect was a major setback in
another area.
To put it very simply, I am sitting in
front of my computer hacking out this
column with one hand because my left
arm is in a sling. It seems that I acci-
dentally ripped a muscle in my left
shoulder: something called the rotator
cuff. Talk about pain! The worst part
about the injury was how 1 did it. I
didn't do it while working out with my
wrestlers, or while lifting weights, or
even while out taking my daily run. I did
it while vacuuming out the car! It seems
that I stretched my left arm a little too
far while trying to reach something
under one of the seats.
Well, besides slowing me down a bit.
it has made me a little more aware of
keyboard locations while trying to do
everything with just one hand. After all,
that is what both of these CoCo Keys
programs are about anyway. Call it
poetic justice if you must. All I know is
that I was lucky to get the program done
before the injury took place. 1 only had
to go through the inconvenience of
writing the article this way.
However, that brings to mind what
the real purpose of writing these pro-
grams is all about. Working with hand-
icapped and special needs students
helps keep you aware of what obstacles
others must go through in their lives,
while we take our health and fitness for
granted. Just last week we had a group
of handicapped students address our
student body about the dangers of
alcohol and drug abuse.
The students and young adults were
from an outreach program called
Operation Street Smarts from Lynn,
Massachusetts. Some of the members of
the group were wheelchair bound as a
result of drug or alcohol use or alcohol-
related accidents. One person was
paralyzed from the waist down and only
had limited use of one hand. These
people are limited in their actions and
abilities for the rest of their lives.
Looking back at that week makes my
minor injury seem totally insignificant.
1 suppose that minor accidents help us
keep things in perspective.
One thing I have gotten from this
experience is greater resolve to have
even just one of my programs help
overcome the handicaps of others.

THE RAINBOW August 1987
What suggestions do you have? Any
ideas? Write and let me know of a need
that our CoCo could help meet for a
handicapped person. Later I'll tell you
how this program now seems to be
helping one such student: a 17-year-old
named Chris.
The Program
Type in the listing exactly as you sec
it, including all commas found in the
DATA statements. Failure to do this
correctly will result in an OD Error. The
DATA statements at the end of the
program starting with Line 1000 and
ending in Line 5000 are reserved for you
to insert your own spelling or game
words. 1 have included some simple
words and their phonetic sound so the
Speech Pak can pronounce them in a
way the user can understand. You must
remember to use two entries for each
line: the correctly spelled word and the
phonetic pronunciation.
Using the Program
This program can be used in two
different ways: as a spelling program
with speech or as a keyboard recogni-
tion game involving spelling words,
without speech.
On running the program, you will see
a solid-colored screen, either red or
blue. If the screen is red, press ENTER
to proceed. If the screen is blue, then
press reset and run until the screen is
red. This will help set up the graphics
keyboard with the correct color pattern.
Talking Version
If you are using the Tandy Speech
Pak, press T for talking when the title-
card appears. (Be sure to plug in the Pak
with the power off on your CoCo before
loading the program.) The computer
will repeat the spelling word twice, and
then you must match the flashing keys
on the screen to the correct keys on the
keyboard. As a correct key is pressed,
the letter will be spoken by the comput-
er. Press the wrong key and the screen
will flash.
As you press the correct keys, the
word will be spelled out at the bottom
of the screen. If at any time you want
to check your score, hold down SHIFT
while pressing the CLEAR key. You may
continue by pressing C. The score card
operates like all our other score cards
from our other "Wishing Well"
programs.
As you can tell by now, the program
will actually spell out each word for you
by flashing the corresponding key on
the screen. It is not testing the user on
the spelling. Instead, it is helping the
user go through the steps of learning
and reinforcement. It can be a big help
in learning new words. (Note: The
words must be 10 letters or less in
length.)
Non-Talking
If you do not have a Speech Pak, you
can use this same program in a slightly
different way without making any other
changes. Simply press N for non-
talking; the program works in the same
way without talking. However, this way
the program becomes a game to see if
the user can quickly match the flashing
key to the keyboard and guess the
spelling word. The teacher or parent can
sit with the student to prompt him or
her along. You could even use a stop-
watch to time how quickly all the words
are correctly spelled. (I didn't want to
write that routine into the program
because different CoCos, new and old,
have different clock speeds sometimes.
It wouldn't be as accurate.)
Believe me, students will even enjoy
using the program in this way. It does
not need speech to be a hit. The graphics
alone will get it by.
Using Your Own Words
To use your own spelling words,
dump mine by entering:
DEL1000-4999
Line 5000 must be:
DATA END, END
Keep your words under 10 letters in
length. Use one word with its pronun-
ciation per line. Separate each by a
comma, such as:
1000 DATA DIRT,DURT
You may include up to 99 such words,
but I wouldn't use that many. The
program would take too long to run.
Ten to 20 is usually a good number. Be
sure to save your new version with a
Field Test
As soon as I completed this program,
one of my fellow teachers suggested 1 let
one of our students, Chris, try it with
his spelling words. Chris still has diffi-
culty with simple words such as "stop,"
"taxi," "if" and "the."
I put about 10 of these words in the
CoCo and let him try. While being very
limited in ability, he has taken to the
program like a duck to water. He really
enjoys using the program and, after
only a few days, is able to guess the word
after only a few letters. (Special needs
students sometimes have a problem
with closure: completing a word, sent-
ence or picture if part is missing.) This
program will now become part of his
daily routine.
Conclusion
I hope you all can become more
appreciative of those who have limited
abilities. Helping them can be a big part
of making your day. While this program
didn't start out that way, the end result
fit that picture perfectly. I hope some of
you can come up with suggestions on
helping others with handicaps by using
our CoCo.
Until then, I'm going rest a bit and let
my car get a little dirtier than usual. □

'One-Liner Contest
"has now been expanded
to include programs of
either one or two lines. This
means a new dimension and new
opportunity for those who have "really
neat" programs that simply just won't fit in
one line.
Here are the guidelines: The program must
work in Extended basic, have only one or two
line numbers and be entirely self-contained —
no loading other programs, no calling ROM
routines, no poked-in machine language code.
The program has to run when typed in directly
(since that's how our readers will use it). Make
sure your line, or lines, aren't packed so tightly
that the program won't list completely. Finally,
any instructions needed should
be very short.

EDUCATION NOTES
Number Fun
for the Very Young
By Steve Blyn
Rainbow Contributing Editor
This month's program is geared to
preschoolers and children in
early primary school. It is a
review of the numbers 1 through 9. We
are aiming at reinforcing which number
comes before and after each of these
numbers. In the beginning, children will
no doubt need some adult assistance to
read the directions. However, after they
have played the game for a while, many
will probably be able to proceed inde-
pendently.
There is no scoring or true end to this
program. We feel it is pointless to give
a child this young a numerical score.
Frequent graphics and musical rewards
are more appropriate for this age group.
After any example, the child may either
press the ENTER key to go on or the E
key to end the program.
There is little pressure when incorrect
answers are given. Nothing at all
happens if any of the letter keys are
pressed. A short sound is heard if a
wrong number is pressed. The child can
make as many attempts as he needs to
get the correct answer.
The program only proceeds when a
Steve Blyn leaches both exceptional
and gifted children, holds two master's
degrees and has won awards for the
design of programs to aid the handi-
capped. He owns Computer Island and
lives in Staten Island, New York.
correct response is made. A pleasant
tune is played and graphics are drawn
on the screen. The graphics are random
figures of a triangle, circle and square.
This adds an extra dimension to the
program; the three figures are often
learned at about the same age as these
numbers are studied.
Reinforcement is therefore only for
positive answers. This is in keeping with
our longstanding policy of presenting
no discouraging feedback to the very
young child. We only want them to have
positive feelings toward their comput-
ers. Early experiences and feelings may
certainly carry over to later ages. We
want no child to "turn-off" to comput-
ers at any age, least of all at an early age.
The program begins by executing a
GDSUB to Line 390. Lines 400 through
650 read the strings to draw the letters
and numbers that are needed. The
program then returns to lines 40
through 90, which set up the high
resolution screen and print the words
"Which Number Comes." Line 110
decides whether the question will read
"Before" or "After." Either of these
words then becomes 00$ on Line 140.
Line 150 prints the number in question
as Z$.
The number we are looking for is the
variable R. If the word "Before" was
selected, then R=R-1. Similarly, if the
word "After" was selected, then R=R+1.
Lines 120 through 130 take care of this
job.
Lines 160 through 270 draw a ran-
dom triangle, circle and square. This is
done to both reinforce learning these
three shapes and to add some more
pizazz to the program. We have found
that it is a good idea to add as much
color, sound and interest as possible to
programs targeted for early childhood
or preschool youngsters. They can often
be distracted away from the computer:
An extra graphic here and there never
hurts in holding their attention.
Lines 280 through 330 get and eval-
uate the child's answer. If correct, the
graphics appear and a happy tune is
played. If an incorrect number is
pressed, a short tune is played. After a
correct response, the child is prompted
to press ENTER. Only by pressing ENTER
will another example be displayed. The
program will end if the E key is pressed.
Please feel free to alter this program
to suit your needs. One suggestion is to
change the three geometric figures used
if your child or class tires of them.
Another fairly easy modification would
be to alter the program for the numbers
from 10 to 99.
We at Computer Island hope your
youngster learns a little and has fun
playing with this program. As always,
we enjoy hearing about your experien-
ces with our programs. D

Hint . . .
Solves Printer Predicament
For some time, my 3-year-old Gemini 10X has been
shoving the ribbon up above the pins, thereby printing
several blank spaces. To correct the problem, I had
been holding the ribbon in place with a pencil on either
side of the print head. On a recent visit, my son was
able to help me out of this predicament (a welcome
relief, as holding the ribbon manually was a real pain
in the back).
He carefully removed the printer head and pointed
out the large amount of dried ink stuck under the
plate. After removing the offending material, he
replaced the head and the printer works great. If your
printer has these symptoms, you might want to try this
procedure. Just be very careful when working with the
small print head parts — new heads are still somewhat
expensive.

DELPHI BUREAU
The Battle Line Is Being
Drawn
Since il started in September 1985,
the CoCo SIG has steadily grown
to become one of the largest and
busiest SIGs on Delphi. While the SIG
staff certainly deserves a lot of credit,
the SIG members themselves are the
most important reason for this growth.
To a large extent, we have tried to mold
the CoCo SIG in a fashion that would
be of most service to its members. We
are now introducing a new aspect to the
SIG, which will greatly enhance its
information value.
Beginning in the month of August,
members of the CoCo SIG will be
allowed to participate in what is called
Battle Line. Each month, a subject will
be chosen and SIG members are invited
to share their views on that subject. We
will offer conferences that may well turn
into controversial debates, and all are
invited to attend. These conferences will
be looked upon as a no-holds-barred
opportunity for everyone to express
their viewpoints. In addition, through-
out each month, polls will be posted in
the Polls section and the Forum will be
used by members to express their views.
At the end of each month, all Polls,
Forum messages and conferences re-
lated to the Battle Line subject will be
archived in the database for later pe-
rusal by members. The OS-9 Online
SIG will also be running Battle Line and
may or may not be discussing the same
subject as the CoCo SIG.
Cray Augsburg is rainbow's technical
editor and has an associate 's degree in
electrical engineering. He and his wife,
Ruth Ann, have two children and live
in Louisville, Kentucky. His username
on Delphi is CRA Y.
102 THE RAINBOW August 1987
By Cray Augsburg
Rainbow Technical Editor
Battle Line will give everyone a
chance to "get on a soapbox." While we
will be in charge of picking the topic
each month, all members are encour-
aged to suggest ideas for these topics.
We also expect SIG members to volun-
teer to lead a conference. When Battle
Line becomes a big hit, it is very possible
we will shorten the time devoted to each
subject. Instead of a month, we might
discuss a topic for a week or two weeks.
This all depends on the reaction of the
SIG members to Battle Line.
The Battle Line topic for August has
not been chosen at the time of this
writing, so go ahead and send your
suggestions to Jim Reed (JIMREED) or
Marty Goodman (MARTYGOODMAN)
via Mail or Forum. To suggest topics for
Battle Line in OS-9 Online, contact Jim
Reed or Greg Law (gregl). In the
interest of letting everybody in on it, we
do ask that you try to use the Forum as
much as possible. For more details,
watch the Forum for messages.
New Delphi Handbook
Michael A. Banks (KZIN), SIGop of
the Science Fiction SIG on Delphi, has
been fairly busy writing a new manual
DATABASE REPORT
Following the introduction at RAIN-
BOWfest of an ouistanding graph-
ics editor. Color Max 3, a lot of
interest has been focused on generating
and converting pictures to use with it. For
instance, many of the Atari ST graphics
screens can be converted very simply into
a display format that is compatible with
the CoCo 3. Many of the uploads we've
seen this past month have been graphics
related.
Many users are also interested in con-
verting their favorite game programs to
make use of the enhanced capabilities of
the CoCo 3. One by one, users are upload-
ing their best games, converted for the
CoCo 3.
OS-9 Level II is becoming available in
most areas around the country, and users
are hard at work writing patches and
applications for it. The OS-9 Online SIG
is busy with contributions from users
across the country.
OS-9 Online
In the Graphics topic area, Toni Ryan
(TNTRHODAN) sent us BDRflW . ftR, a BAS1C09
procedure that demonstrates a mouse
interface, graphics pointer and menu
handling. Kevin Darling (kdarling) sent
us some Level II pictures and a Level II
picture loader. These two pictures. Pharoh
and Saturn, arc converted Atari ST pic-
tures in VEF (VDG Enhanced) format.
They may be viewed using the Pix program
that is also in the Graphics topic of the
database.
In the Users Group topic. Greg Law
(GREGI.) has posted seven more additions
to this expanding section of the database.
New groups include basutil, a package of
two assembly routines to set the user ID
number one to return the name of the
driver that is in use; CHKNG, a checkbook
program; CAT, a UNIX-style file concate-
nation utility; CB, which reformats C
for Delphi over the past six months. The
new book, DELPHI: The Official
Guide, is being published by Brady
Books, a division of Simon and Schus-
ter. Through Delphi, the 400-page book
will sell for S19.95 and includes a
coupon for two free online hours for
new subscribers. Unfortunately, present
subscribers will not be able to use this
coupon.
DELPHI: The Official Guide is di-
vided into four major sections. The first
section, "Getting Started," deals with
sign-up and logon procedures. The
second section discusses the menu
concept and how it is employed on
Delphi. Also, this section covers the
system commands, such as SEND and
/WIDTH, and control characters. The
third section details each area of Delphi
and discusses how they can be used.
Coverage of topics like Mail, the Li-
brary and SIGs will be included here.
Rounding out the book is the reference
section, where various network
numbers are listed. This section in-
cludes a glossary of terms and a trou-
bleshooting guide.
Polls, Polls and More Polls
RAINBOW columnist Richard White
(DlCKWHITE), author of "Bits and Bytes
of BASIC," has been chosen by Jim
Reed to serve as Polls Manager. Rich-
ard's duties will include editing new
polls and archiving old polls to make
room for new ones in both the CoCo
SIG and OS-9 Online. And speaking of
new polls, Richard has just finished
archiving several old entries, so there is
plenty of room for you to create a
survey on those subjects dearest to your
heart.
Upcoming Changes
Delphi has told us that they have
started "phase two" for the system
changes in the Database area. Some of
the more important (and most wished
for) changes to be made are:
• Providing a clearer indication be-
fore a download is initiated of
whether a particular file is in ASCII
or binary format (Text vs. Non-Text).
• Allowing semiautomatic download
of all files in a given group. This
change will become more important
as software writers start allowing the
use of Kermit on the CoCo.
• Changing the DOWNLOAD option at
the RCTION> menu to allow the user's
choice of Xmodem, Kermit, buffer
capture, etc., with this choice remain-
ing in effect throughout the session
unless overridden. Delphi also hopes
to allow a Profile setting lor preferred
download method.
• Allowing "serialized" downloads
of programs so that the system will
send Mail to the owner and down-
loader registering serial numbers.
This will be a great boon to shareware
uploaders.
• Increasing the number of possible
topics allowed in the database. At
present, all SIGs are limited to 16
database topics.
• Allowing users to:
search by ownername.
search by date.
search on more than one topic at
a time.
• Allow a DIR NEW command that
would give a directory of only those
files in a given topic that have been
posted since the last time you entered
the database.
• Changing SUBMIT to respect the
prompt mode you are currently
using. For those who are very familiar
with SUBMIT, this will greatly reduce
the amount of time it takes to go
about your business.
• Allowing 'SEND, 'WHO and MAIL at
the DBASES>, ACTION> and WS>
prompts.
We will try to keep you apprised of
the situation as these, and other,
changes take place. In the meantime,
please bear with the Delphi service
people as they go about making the
changes. There may be times during the
weekdays, for those of you who are on
during this time, when you will find
yourself temporarily "locked out" of the
SIG or Database area. This is a neces-
sary precaution Delphi must take and,
when it occurs, rarely poses a problem
for more than a half hour or so.
programs along the lines of the K&R
manual; and COMM, a smart terminal
program that saves the input text in a
buffer and dumps it to a file later.
In the Applications topic, Sam Johnson
(SDJ9060) has sent us the cutspast utility
written in BAS1C09 for fairly heavy Delphi
users who like to save, file and reread some
of the Forum messages they download.
In the Utilities topic, Kevin Darling has
given us his SCF Editor Plus for OS-9
Level II and more of his utilities for Level
II. Greg Law has posted MOUSE. B09, a
short BASIC09 program that demonstrates
the use of Level IPs system calls to support
a mouse. Greg also provided the file
compression/ decompression utility called
AR.
The Patches topic area was enhanced by
the addition of bootpatch from Dave
Philipsen (DPHILIPSEN). This is a short
script file for patching the 059Boot mod-
ule for faster step rates.
CoCo SIG
In the General Information topic area,
Eric Crichlow (diawa) provided a file from
another person concerning a pirate's
justification of software theft. Greg Miller
(GREGMll.LER) then provided his rebuttal
file. Larry Hess (BOBBIHESS) sent another
side of the issue in this controversial series,
called "Piracy - Another View." Greg
Miller then posted his response. (This
subject is also being discussed in the
Forum.) Marty Goodman, M.D. (marty-
GOODMAN) provided another informative
medical article called "AIDS and You."
Mike Fischer (MIKE88) provided Combus-
tion, a text file describing spontaneous
human combustion.
In the Source for 6809 Assemblers topic
area, Mike Tolbert (MIKEGT) posted the
EDTASM source code for his B0DT3.BH5
utility. B00T3 is a version of the popular
utility BOOT, which has been rewritten by
Mike to support a similar function on the
CoCo 3. I posted an Assembly Language
tutorial in response to a user's question
about how to test for the key combination
of SHIFT and ENTER.
Mike Ward (MIKEWARD) posted his
excellent utility EDTCVT.BIN, which will
convert EDTASM source code files contain-
ing embedded tabs into standard ASCII
files. Tab characters are entered into
EDTASM files whenever you use the right
arrow key to advance to the next field.
These tabs are stripped by BASIC and most
word processors, which can result in
unusable files for a user. Mike's utility
cures this problem.
Roger Krupski (hardwarehack) pro-
vided source code for his excellent Morse
Code Generator utility. Those interested in
studying for an amateur radio license will
appreciate Roger's contribution.
In the Utilities & Applications topic-
area. Glen Hathaway (hathaway) pro-
vided T.BIN, a short M/L program that
demonstrates horizontal and vertical
scrolling on the CoCo 3. Roger Bouchard
(HARB1E) provided his DFIX Fix file for
converting Steve Bjork's DFIX utility for
operation with ADOS. Roger also sent us
a multiple disk formatter utility for those
with multiple drives.
Mike Fischer sent us a BASIC program
that contains his favorite patches for Disk
BASIC. Brian Wright (POLTERGEIST) sent us
August 1987 THE RAINBOW 103
his ASCII print utility for producing a
hard copy of text files and his Super DOS
utility. I provided a cataloger program for
disk libraries. Charles Pippin (cwp) sent us
his checkbook program for the CoCo 3.
In the Games topic area, Stephen Macri
(DRACMAN) provided his newest game
called ACEY2C. Jim Pogue (J1MPOGUE)
provided an interesting Scrabble program,
and Dave Ferreira (SKEEVE) provided a
welcome converted Star Trek program for
the CoCo 3.
Tom Chcvrette (shazac) gave us an
outstanding Escape Adventure game that
contains 29 files and consumes nearly an
entire disk. The graphics screens in this
program are very good. Andrew Robinson
(AROB1NSON) sent us a patch program that
enables you to play the popular game
Pitslop II in color when using an RGB
monitor. Brian Wright gave us two games,
called Hotel CoCo and CIA Operative.
Kurt Stecco (HIGHRAILER) provided a
program for booting some CoCo 3 game
programs in color.
The Graphics topic area was enriched
greatly by Greg Miller (GREGMILLER), who
provided us with excellent renditions of
Daffy Duck and Bugs Bunny. Both of these
pictures are very well done, and quite
colorful as well. Bob Montowski (graph-
icspub) sent us a fine addition of Snoopy
and the Red Baron in MGE format.
Robert Pierce (rpierce) sent us his
Diddles program, and Mark O'Pella
(MDODELPHI) provided an XPAD pro-
gram for the CoCo 3. Also, Bob Wharton
(bobwharton) sent us his fine collection
of American League baseball team logos
for the CoCo 3. Roger Bouchard sent us
the specifications for the Tiny files, as well
as his own ST file conversion utilities.
Roger also sent us five outstanding ST
pictures that have been converted into the
MGE format.
Brian Wright gave us his lengthy file
called Pinup Bonanza and a Fan Genera-
tor graphics demo. Eric Crichlow provided
us with some excellent CoCo 3 graphics,
including a graphics tribute to Steve Bjork,
a picture of an Atari ST displaying a
moving waterfall graphic, some proposed
title screens for game programs, and an
excellent animated waterfall demonstra-
tion. Eric Tilcnius (tilenius) sent us his
Cvlogo basic program. As you can tell,
the graphics topic was really busy this
month!
The Music & Sound topic of the data-
base has also been very busy. The largest
contributor to the Music topic, by far, is
Bill Starr (wstarr). Bill has graciously
donated a total of 82 files to date, amount-
ing to almost 300 kilobytes of music files!
If you're serious about Orchestra-90 1 CC,
then Delphi is definitely the place for you
to be! Bill's uploads cover practically every
type of music, from oldies, country and
ragtime, to popular, Latin and jazz.
Gary McCarty (bandman) provided
several Orchestra files also, including
Maple Leaf Rag, Easy Winners, Solace,
and Battle of Shiloh. Bryan Eggers (soft-
affair) provided a text file describing how
to write music for Orchestra-90.
The Data Communications topic was
the scene of much excitement when Rick
Adams (rickadams) uploaded the long-
awaited Version 2.0 of Rickeyterm. This
latest version provides support for the
standard serial port on the CoCo 3 for
communications at 300 or 1200 baud. If
you still want to use an RS-232 pack,
Rickeyterm will then provide online print-
er support. Brian Wright gave us a file
describing how to set up a new Avatex
1200-baud modem. 1 provided a short text
file describing where and how to obtain the
three most popular CoCo terminal pro-
grams, namely, Greg-E-Term, Mikey-
Terin, and Rickeyterm.
As you can see, this past month was a
busy one for us. User activity was ex-
tremely high, and the Conference areas of
the SIGs were always buzzing. We hope
you'll join us on Delphi soon!

The Rainbow Introductory Guide to
Statistics
Most people have been using statistics since they learned
to talk. Statistical results and concepts turn up everywhere.
A large part of our daily news consists of statistics. Results
of opinion polls, surveys, research studies, the Dow Jones
industrial average and, of course, our sports news are all
statistics. But statistics are often misused. The informed
person needs to understand the basic concepts in order to
judge the appropriateness of applications.
Rainbow Contributing Editor Dr. Michael Plog and co-
author Dr. Norman Stenzel have written The Rainbow
Introductory Guide to Statistics just for beginners. It is an
easy-to-understand guide to this sometimes mysterious area
of mathematics. Their aim is to introduce readers to the
realm of statistical processes and thinking, and they believe
that the Tandy Color Computer is an ideal machine for the
reduction of data.
Sharpen your skills with The Rainbow Introductory
Guide to Statistics for only $6.95. Included in the book is
the CoCo-Stat program, a BASIC statistics program just for
the Color Computer. (80-column printer required.) Forget
the typing hassle by ordering the accompanying Statistics
Tape or Disk for only S5.95. Spend your time learning and
enjoying the new material, not debugging your typing. Just
pop in the tape or disk and you're ready for action!

THE RAINBOW August 1987
Rootin' Tootin'
Sharpshootin' CoCo
By Albeit P. Marsh
Ready for a great new game for
the CoCo 3? Shoot'n Range is
a fast-paced action/ strategy
game that takes full advantage of the
CoCo 3's possiblities.
In this game, you are developing your
sharpshooting ability at the local, offi-
cial practice range. Armed with the
most advanced push-button-activated
solar laser gun, you are determined to
shoot as many happy-faced targets as
you can. With just one touch of the
trigger, you can take revenge on those
optimistic androids.
Of course, this man versus machine
battle is not all that easy. In order to
continue using the shooting range, you
must keep your hit/ miss percentage
above 50 percent. Every shot costs you
a certain amount of energy, determined
by you (check the power gauge on the
right side of your tracking monitor).
Also, because of the new solar cycle bill
passed by Congress, your gun will only
re-energize every 10 rounds of play. So
pick up that gun, aim carefully and fry
some silicon.
Shoot 'n Range requires a CoCo 3 and
will work with any type of color display.
You control the horizontal movement
of the gun, along with the power
amount, by using the right mouse/
joystick. Use either button to fire the
laser.
Enter the listing carefully then save
and run it. As soon as the program
starts, you see a screen prompting you
to enter the display type you are using.
If you are using an RGB monitor, such
as the CM-8, press the 1 key on the
keyboard. If you are using a television
or composite monitor, press the 2 key.
After a short delay, a title screen
appears. Press any key except BRK/ESC
to continue the program. The next thing
you should see is the playing field.
Across the top, your score, hit/ miss
percentage and the gun's power level are

quirements and more. Get down
on the basepaths with Color
Baseball — it plays just like the
real game! Or get into role-playing
secret agent action with the
Interbank Incident and recover a

Make learning fun
One of the most valuable poten-
tials of your Color Computer is giv-
ing your children a head start in
education. We've got programs for
kids of all ages that will give them
hours of productive fun.
Younger children will learn with
Color Math — older kids will enjoy
developing logical problem-solving
skills with Robot Odyssey, which ex-
plores the concepts of electronic
circuitry, circuit design and logic.
And there are also entertaining
teaching programs featuring popu-
lar Disney characters like Winnie
the Pooh, Mickey Mouse and
Donald Duck. You'll find programs
that develop hundreds of skills.

displayed. Your laser pistol is at the
bottom, and a marker on the right side
of the screen shows the amount of
power needed for that shot.
The targets appear out of the ground.
Each round completed decreases the
length of time the targets stay above
ground. More targets are added every
five rounds, and the speed slows back
down again.
There can be a total of 10 targets on
the screen. If you get past Level 20, there
will be 10 targets on the screen, plus two
that will appear after there is room for
them.
Position the gun so it is directly under
the target you want to hit. By moving
the power gauge up and down with the
controller, you can determine how far
your shot will go.
Even though you will still hit the
target, be careful not to overshoot. By
doing so, you will be wasting power.
You only start with 5,000 units of
power, which is increased
by 3,000, plus 200 times
the number of rounds
you completed every 10
rounds. For example,
after 10 rounds you re-
ceive 5,000 units of
power, after 20, you re-
ceive 7,000 units, and so
on.
The game is over when
you either run out of
power or your percentage
drops below 50 percent.
You are then asked if you
would like to play again.
If you press the BRK/ESC key, you will
be asked if you want to restart. Answer
these questions by pressing Y for yes or
N for no.
I hope you enjoy playing Shoot 'n
Range as much as 1 enjoyed creating it.
If you have any questions, comments or
suggestions, please feel free to write.
Good luck and have fun gaining a
little revenge on modern technology.

" I cannot imagine the CoCo 3 without ADOS-3;
it would not be a complete machine."
The RAINBOW, July 1987
You've moved up to a CoCo 3. A powerful new machine. Now. it's time to give BASIC a shot in the arm. with ADOS-3.
Wouldn't it be nice to turn on your machine and be greeted by an 80-column display, in the colors ot your choice,
with your own custom startup message? To run routinely at 2 MHz (double speed) without having to slow down for
disk and printer operations? This and much, much more is possible with ADOS-3, our CoCo 3 adaptation of Ihe
acclaimed original ADOS, which shares the original's virtual 100% compatibility with commercial software. After
customizing ADOS-3 using the provided configuring utility, you can have it burned into an EPROM that plugs into
the Disk BASIC ROM socket, or just use it In RAM as a disk utility. (EPROM + burning will cost S15-20; we provide
information concerning how you can have this done.) Supports double-sided drives (35, 40. or 80 tracks). FAST and
SLOW commands, auto line number prompts, RUNM command, keystroke macros, arrow-key scroll through BASIC
programs, auto-edit of error line, and many more valuable features.
"ON A SCALE OF 1 TO 10, I RATE ADOS-3 A SOLID 15."

WE'RE BRINGING THE COCO
RAINBOW'S
BROADENING ITS
SPECTRUM
the rainbow and the Delphi Infor-
mation Utility have joined together
to allow CoCo owners all over the
world to connect with one another!
Delphi is a full-service information
utility. It offers everything from up-
to-the-minute news stories from The
Associated Press to electronic mail
services. But, best of all, it now has
a special forum for Color Computer
owners, and it's operated by the
people who bring you the rainbow
each month.
The CoCo Special Interest Group
(SIG) features a variety of services,
including an open forum where you
can send and receive messages
from Color Computer owners all
over the world. It also has several
databases to which you can upload
your favorite programs and from
which you can download programs
written by other CoCo enthusiasts.
Some of these databases are basic
programming, OS-9 and home ap-
plications.
When setting up your account with
Delphi, if you do not have a credit
card or prefer not to use it, Delphi
requires that you send $25 to give
your account a positive balance.
This will be refunded after your first
free hour if you choose to no longer
use the system or it will be applied
to future connect charges. If you do
not maintain a positive balance, you
will be charged $3.50 each month
for direct billing.
PEEK INTO THE
RAINBOW
The CoCo SIG's conference feature
allows you to meet electronically
with other members of the CoCo
Community. You can join conferen-
ces with notables such as Dale
Puckett, Cray Augsburg, Marty
Goodman, Don Hutchison, Jim
Reed, Lonnie Falk and others — on
a regular basis. Conference sched-
ules will appear in the rainbow
each month. Be sure to check online
announcements for changes and
additions.
THE OTHER SIDE
OF THE RAINBOW
On Delphi, you also are able to buy
rainbow on tape — order a whole
set, or download an individual pro-
gram immediately. You can also
renew your rainbow subscription,
make a fast and easy order for soft-
ware or hardware from a multitude
of vendors, or inquire about prod-
ucts on the CoCo SIG.
We also have a number of programs
that you can download and use, just
for the cost of the time you spend
transferring them. There'll also be
corrections for rainbow articles,
helpful hints and many other useful
features.
FREE LIFETIME
MEMBERSHIP
the rainbow is offering subscribers
a free lifetime subscription to Delphi
— a $29.95 value — and a free hour
of connect time — a $7.20 value at
either 300, 1200 or 2400 Baud — so
you can sample Delphi and the rain-
bow CoCo SIG. That's right. Your
subscription to the rainbow entitles
you to this $37.15 value as a free
bonus!
If you're not a rainbow subscriber,
just enter your order when you sign
on with Delphi and you'll get the
same great deal! For our $31 sub-
scription fee, you'll get the finest

COMMUNITY TOGETHER
How to reach RAINBOW'S Color Computer SIG . . .
There are several ways to connect to Delphi and THE
rainbow's CoCo SIG. In most cities you will not even have
to pay long distance charges; you can use special data
communications networks like Telenet, Tymnet and the
Canadian Datapac network.
First, set your terminal program to operate at either 300
or 1200 Baud (depending on the modem you have), and
also select either 7 bits with even parity or 8 bits with no
parity, and one stop bit. (If one combination doesn't work,
try another.)
Decide which network you should use. There is no
surcharge for Telenet or Tymnet. Canadian residents using
Datapac will be charged an additional $10.80 (U.S.) per
hour.
On Telenet: Call (800) 821-5340 to get the Telenet
number for your area. After you call the appropriate
number for your own area and make connection, you'll
see a prompt of "L?" Press ENTER, the period key (.) and
ENTER again. At the "service:" prompt, type GVC (for
General Videotex Corporation) and ENTER.
On Tymnet: Call (800) 336-0149 to get the Tymnet
number for your area. After you dial your designated
number and connect, you will see either "garbage" or a
message saying "please type your terminal identifier." At
this point, even if the screen is garbled, simply press 'A'.
When "please log in:" appears, type DELPHI and press
ENTER.
From Canada (on Datapac): Call Delphi Customer
Service at (617) 491-3393 to get the Datapac number for
your area. After you connect, press the period key ( . ) and
ENTER (use two periods if you're using 1200 Baud). Type
SET 2:1, 3:12G and press ENTER. Now type p 1 310S,
DELPHI ; and press ENTER. Including the $10.80 per hour
surcharge, Canadian residents using Datapac are charged
a total of $18 (U.S.) per hour for connect time, day or
evening.
From other countries: Many countries have their own
data networks that can connect to either Telenet or
Tymnet. Check with the telephone authorities in your
country for details on how to sign up for this service. When
you have an account set up, you can reach Delphi with
a "host code" of 3 1 1 6 1 70 3088 through Telenet, or 3 1 06
90 6015 through Tymnet. (You'll have to pay the toll
charges for this connection.)
Type in Your Username
If you're already a subscriber to THE RAINBOW, at the
"USERNAME:" prompt, type JDINDELPHI and press
ENTER. At the "PASSWORD:" prompt, type RAINBOW.
Then, at the "NUMBER:" prompt, type your individual
subscription number from the mailing label of your latest
issue of the rainbow. (If there are one or more zeros at
the beginning of this number, include them.)
If you don't already have a subscription, at the "USER-
NAME:" prompt, type JDINDELPHI and press ENTER. At
the "PASSWORD:" prompt, type SENDRHINBOW and press
ENTER. Have your MasterCard, VISA or American
Express card ready, because you'll be led through a series
of questions that will enable us to put your RAINBOW and
Delphi subscriptions into effect. In an effort to hold down
non-editorial costs, we do not bill for subscriptions.
If you make a typing error, just use Control-X and start
over. Remember that at any point, when you're on Delphi,
you can type HELP to get help on how to use the system.
To get off the system just type BYE.
If you find that you're unable to log on to Delphi and
enter the CoCo SlG after following these instructions, call
us during afternoon business hours at (502) 228-4492. We'll
be glad to offer assistance.
Come Visit Us! Type: GROUP COCO
A I tcr you sign in, you'll be prompted to set up your own,
personal "username" — Delphi is a friendly service, no
numbers to remember — and you'll be asked a number
of questions so Delphi can set up your account. You'll also
be assigned a temporary password.
Delphi will tell you that your account will be ready after
6 p.m. the same day if you sign up before noon (Eastern
time zone.) If not, your account will be ready at 6 p.m.
the next business day. Once an account is verified and
opened, each RAINBOW subscriber will be credited with an
hour of free lime!
When you log back in, use your chosen username and
your temporary password to access the system. At that
point, you will meet Max, who will help you configure
things and will change your temporary password into your
own personal password. This is the password you will use
for subsequent sessions — or until you change it.
After Max bids you goodbye, you'll wind up at the
Delphi Main Menu; type in GROUP COCO and join us on
the CoCo SIG!

Rescue
116 THE RAINBOW August 1987
The astronauts
stranded on the
moon are counting
on you!
By Clyde Johnson, Jr.
Zunar Rescue is an arcade game
for a 32K Color Computer. It re-
quires at least one joystick. You are
a member of the Lunar Rescue Squad,
in charge of the safety of all the
astronaut-explorers. To rescue astro-
Clyde Johnson, Jr. is a student at
Embry- Riddle Aeronautical University
in Daytona Beach, Florida. He is ma-
joring in aeronautical engineering and
has had his color computer for five
years.
nauls stranded in the mountains, you
must pilot your spacecraft to them, pick
them up with the ladder, and take them
to the next base. Your fuel supply is
limited so there is no time to waste.
After running the program and
choosing a starting skill level, the game
screen will appear. Your ship is on the
lower-left side of the screen, the astro-
naut you must rescue is in one of the
valleys of the mountain range, and the
base you must fly him to is on the lower-
right side of the screen. The bottom of
the screen is your control panel and
displays altitude, vertical velocity, fuel
remaining, and other necessary infor-
mation. The ship is controlled with the
right joystick, and pulling the stick back
adds downward thrust; the farther back
you pull, the more thrust. To take off,
pull the stick all the way back and hold
it there until you are clear of the base.
To pick up the astronaut, maneuver
your ship over him and press the fire-
button to drop the ladder. You have
only 30 seconds to pick him up before
you must close the hatch; therefore, you
must be in position to get him before
you drop the ladder. The ladder must be
positioned directly over him and extend
below his feet. The extra weight of the
astronaut will pull the ship down, so be
prepared to add thrust when he is
aboard.
After picking up the astronaut, or at
least before running out of fuel, you
must land at the base. To do this you
must be completely over the flat area on
the right side of the screen and touch
down with a velocity less than 10. You
will be given a score based on your
performance and, if you successfully
rescued the astronaut, you will advance
to the next level.
When typing in this program, be sure
to save it to disk or tape before running;
a machine language routine is used that
could crash your computer if any typing
errors are made. This routine also
disables the BREAK key so you must
press reset to exit the program.

Also from Falsoft, The RAINBOW MAKER,
The magazine for Tandy portable and MS-DOS users
Not only does Tandy produce our favorite CoCo, we think they produce the best and best-priced lap-
top portable and MS-DOS computers as well. We've found that when satisfied Color Computer users
decide to add portability or move to MS-DOS, many stick with Tandy. For these people we publish PCM,
The Personal Computer Magazine for Tandy Computer Users.
Each month in PCM, you'll find information and programs for the Tandy 100, 102, 200 and 600 portable
computers. And you'll find even more coverage for their MS-DOS machines, the 1000, 1200, 2000 and
3000, along with the great new 1000 EX, 1000 SX and 3000 HL.
FREE PROGRAMS!
We learned from the rainbow that readers want programs to type in, so each month we bring you an
assortment of them: games, utilities, graphics, and home and business applications.
BAR CODE LISTINGS AND PROGRAM DISKS!
For portable users, PCM is the only home computer publication in the world that brings you programs
in bar code, ready to scan into memory like magic with the sweep of a wand! For those who don't have
time to type in listings, we offer a companion disk service with all the programs from the magazine.
TUTORIALS AND PRODUCT REVIEWS!
As if all this weren't enough, we offer regular tutorials on telecommunications and hardware; assembly
language, basic and pascal programming tips; and in-depth reviews of the new software, peripherals
and services as they are released. Add it all up and we think you'll find PCM to be the most informative
and fun magazine for this market today!

TURN OF THE SCREW
Clever Uses for Memory
By Tony DiStefano
Rainbow Contributing Editor
Many years ago, when the
CoCo first came out, I was
studying the memory map of
the CoCo's CPU. I had only 4K of
memory then, but soon realized that
this CPU could access a lot more. In
fact, everyone should know by now that
the CPU in the CoCo can access 64K
of memory.
I soon upgraded to I6K; that was
easy. Then I read an article about
upgrading the CoCo to 32K using a
technique called "piggyback." That was
wonderful. I now had a full 32K. Re-
member, this was before the time of 64K
chips. I also had BASIC and Extended
BASIC. That was another 16K, making
a total of 48 K of memory. There was
16K left, which was reserved for the
cartridge slot. I started to wonder how
I could put more memory in there. 1
now have a CoCo 3 with 512K, and I
am still asking myself the same ques-
tion!
1 looked in what were then the latest
catalogs on memory chips and came
across a memory chip called a 2114.
This is a IK- by four-bit static RAM
chip. Static RAM means it does not
have to be refreshed as does dynamic
RAM. It took two of these chips to
make IK of RAM. But I was desperate
for more RAM, so 1 bought 16 of them,
hoping to make an 8K RAM module for
the CoCo cartridge slot.
After many hours of work over a hot
soldering iron, I managed to make this
8K module work. It was mapped from
SC000 to SDFFF. (For you people who
still think in decimal, from 49152 to
57343.) It was great; I was the only kid

specialist in computer hardware proj-
ects. He lives in Laval Ouest, Quebec.

on the block to have that memory. I had
many hours of fun with it.
Then came the 64K memory, and out
went the 32K piggyback memory: A
little bit of modification to the board
and a little bit of wiring to the 74LS02,
and presto — 64K of memory. That was
great, but when it came time to use my
8K RAM module, it didn't work any-
more. What the heck, 1 had 64K, so I
just left it. Then I got my disk drive. It
connected to the cartridge slot and there
was no longer room for my 8K module.
I put it on a shelf, where it gathered dust
for many years.
Just the other day, I was working on
something that required a little bit of
memory that was protected. By pro-
tected, I mean I could not write to it
when I needed. That is not the case of
the CoCo in the 64K mode. You can
write to anywhere in 64K when in the
"All-RAM" mode. I thought of using an
EPROM. It would certainly do the job,
but an EPROM is a lot of trouble. You
have to get out the EPROM burner, run
the EPROM software, and erase it
every time you have to start anew.
Well, this wouldn't do, so I went over
to my long-term storage bin and pulled
out my old 8K RAM module. With a
bit of modification, I could make my
RAM module into a ROM module,
with just a switch to control it. Great
idea — only one problem.
When it came time to write to the 8K
module, nothing worked. I couldn't
figure it out. Why wasn't I able to write
to the cartridge area? After a long look
at the CoCo schematic, I figured it out.
When 1 had added the 64K memory
chips, I had done a modification using
the 74LS02. That modification pre-
vented the CoCo from writing to the
cartridge slot area. I was in trouble; my
little 8K module was now useless.
After some thought, I came up with
a solution. It required a little bit of
circuitry, but I was able to write to the
cartridge area. For the circuit I am
presenting here, I didn't want to use 16
chips to make 8K of memory, so I
looked into my newest catalog and
found one chip that replaced all 16 of
the old memory chips. This chip is a
6264, which is an 8K- by eight-bit
memory chip all rolled into one chip;
my, how technology has advanced!
Building this circuit is a two-step
process. With the proper hardware, I set
up a one-byte read/ write memory latch
and a flip-flop, mapped at SFF40.
Remember them, way back when I was
explaining about TTL gates? The first
step is to store or poke a value into the
one-byte memory. I used a 74LS374 for
this, which is an octal latch. When you
store the eight-bit value to that latch,
you also preset half of a 74LS74. This
is a D-type flip-flop with preset and
clear. The output of this flip-flop goes
to one side of a dual-input OR gate. You
now have a valid byte in the latch and
have flipped the flip-flop.
The second step is to read a byte from
the 8K module. Remember that this
read is to the non-writable area from
SC000 to SDFFF, where the module is.
The read does two things; first, it selects
the 8K module. You are reading this
location using a load or a peek com-
mand. But, if you look at the circuit in
Figure I, you will see that the output of
the OR gate goes to the R/W (read/
write) line of the memory. Normally,
when you read from this location, the
R/W line is high, which puts the chip
in the read mode. Now that the flip-flop
is flipped, however, the R/W line will
go low when you read from the area. So,
the memory chip goes into the write
mode.
But, the CPU is reading, and if the
CPU is reading and the memory chip is
writing, where does the data come
from? Well, remember the latch? The
output of the OR gate is also connected
to the Output Enable of our latch. The
memory chip gets its data from the
latch, which is putting its data on the
bus. There is no conflict because noth-
ing else is putting anything on the bus;
the CPU is reading and the memory
chip wants data in the write mode. This
action causes the data that we put into
the latch to be put into the memory
chip. That is how you write to an area
of memory that is not writable. To end
things, when we are finished reading, or
should I say writing, the flip-flop is
flopped back to the original state.
To summarize, every time you want
to write to a location from SC000 to
SDFFF, you must first store or poke
that data to SFF40. That loads up the
latch and flips the flip-flop. Then, read
the location you wanted to write to, to
transfer the data into it. That's all there
is to it! By the way, it is automatically
wrile-protected. You can't write to it
and change the data — that is why I
made this in the first place.
Now for the construction of the
project. There are only four parts to it,
as you can see from the schematic in
Figure 1. In the case of the 74LS74 and
the 74LS32, unmarked pins are unused.
Here is a list of connections to the chips
that connect +5V and GND:

It is recommended that you put all of
these chips into sockets because if you
make a mistake and burn out one of
them, it is a real pain to unsolder all the
connections. You will also need a board
to mount the parts on. You can get such
a board from C.R.C. Computers Inc.,
(514) 383-5293. In fact, they have all the
parts you need. The standard project
building tools are necessary for this
project.
A note to people who are using a
Multi-Pak: In order to use this module
with the Multi-Pak, you must set the
switch to the slot that the module is in.
If you have a disk controller and are
using Disk Extended BASIC, you can
switch to the modules slot by software,
but you will lose Disk BASIC software,
and the computer will crash. A good
knowledge of machine language pro-
gramming and Disk Extended BASIC is
necessary to avoid crashing. The same
goes with the CoCo 3. You can use it
with the CoCo 3, but you must know
how to switch into the ROM/ RAM
mode. Again, a knowledge of the ma-
chine is necessary. □

Looking for CoCo 3 Answers
By Richard E. Esposito
Rainbow Contributing Editor
with Richard W. Libra
/ recently purchased a new CoCo 3
and a Panasonic KX-PI092 DM P.
\M Can you tell me where I can get a
graphics screen dump for my printer
that will at least work for PNODE 1
through 4 screens and possibly for the
new high resolution screens? Do you
know of a non-OS-9 editor for the
CoCo 3 that uses the Hi- Res text
screens and large memory capacity? I'd
like the editor to be invisible and to be
able to enter and execute BASIC com-
mands from inside the editor. lam also
looking for a smart terminal program
that supports the screen and memory
capabilities of the CoCo 3 and emulates
at least a VT52 terminal. Do you know
if anyone has developed a validated A da
compiler package? I have OS-9 Level I
and, after reading the documentation
several times, I can still barely create a
login command file. I have heard many
rumors, accusations and praises about
OS-9 Level II. I would like to use
OS-9, but its user-hostility has made me
afraid of it.

documentation is much better than that

Wants to Use Disk
/ have backed up my ROM packs
using ROM Pack Roundup/row the
October 1984 issue and ROMRAM
from the March 1984 issue. I have been
using most of them successfully with my
previous cassette-based system. I re-
cently purchased a Radio Shack Drive
and find that I cannot get the pro-
grams to execute after saving them to
disk. I would like to use Scripsit, ED-
TASM+, and Spectaculator for creating
disk files once I can get them to execute
from disk. My CoCo 2 was purchased
as a 16K ECB at the end of 1983 and
its serial number is 001698 and model
number is 26-3027. I have since up-
graded to 64K. Another item I am
concerned about is my VIP terminal
programs. The cassette version works,
except when I try to print the buffer. It
prints the first page and then locks up.
Pushing reset is the only way out. The
disk version loads and the title screen
appears, but then an '£" appears above
the title, the disk keeps running, and
nothing else happens.
Brock Beske
Mankato, MN
T2 For programs like Spectaculator
A }C that generate files, the files will
still go to tape. While patching the file
routines is possible, it is no simple task.
The easiest way would be to purchase
the disk versions of those routines. In
that vein, I must ask why Scripsit and
Spectaculator! These are far from the
best the CoCo has to offer. I suggest you
consider disk versions of Telewriter and
Dynacalc as replacements. The VIP
terminal program, to my knowledge, is
no longer marketed. Get a disk terminal

Remote Keyboard
I've read Marty Goodman 's advice to
those having trouble finding room
for the CoCo with Multi-Pak at-
tached. He suggested to "make a remote
keyboard, and put the main CoCo
system below, above, or to one side of
your desk. " Sounds good to me, but
how does one do it? I'm not familiar
with availability or sources for key-
boards nor proper methods for connect-
ing them. If keyboards are too expen-
sive or difficult to hook up, can another
computer, if readily available, hook up
instead of a keyboard? And if so, how?
W. V. Barton
McPherson, KS
ID Hold off a bit on that one. A
/£ number of companies are working
on IBM PC keyboard adapters for the
CoCo. I expect to see them at
RAINBOWfest-Princeton.
Calling ASCII
^ / cannot call up ASCII format pro-
_ grams. I download from other sys-
E terns into BASIC. I have a CoCo 2
with cassette drive and modem D/ L
Program Pak. Can you help?
Andy Brady
Lake Worth, FL
ID After you download the pro-
/C grams, load them into an ASCII
word processor and edit them so that
each line starts with a line number and
there are no statements that continue
onto a second line. Save the files back
to tape and then they should load OK.
Address Conversion
^j BASIC programs for the CoCo are
„ readily transferable to IBM PCs
i using CoCoUtil. However, machine
language pokes within BASIC, when
transferred, yield incorrect code due to
differences in program map location.
Do conversion tables exist for map
location of CoCo Disk BASIC 1.0 or I . I
to a PC BASIC such as GW-BASIC?
Robert Freedman
Mars, PA
ID Unfortunately, the PEEK-POKE
}£ address conversion is not that
simple. From a user's point of view, the
BASICS are quite similar, while at the
machine level they are different to the
extent that a simple PEEK-POKE on one
computer can easily track to a user-
provided machine language subroutine
in the other.
Those Noisy Drives
p / purchased two TEAC FD-55As
_ about two years ago. I have always
_ thought they are pretty noisy,
especially when compared to other
computers like the Tandy 1000. Are
they noisy because they are in a vertical
case or because they are external? They
are supposed to be good drives. Can you
offer any light on the subject?
Robert Jobin
Theodore, AL
"D The older TEAC half-high drives
/£ do run noisy. It is inherent in the
drives' design and not related to their
physical orientation. These drives are
reputed for their reliability, and the
later models (with BV suffix) do run
quieter.
CoCo 3 and the RS-232
/ recently purchased a Color
- Computer 3 and hooked my RS-232
— to it, expecting it to be compatible.
When I typed EXEC8.HC000. the
computer refused to operate the inter-
face. Upon testing the connection and
the DIP switches, I noticed that the Pak
worked only during the computer 's first
cold start. I thought all of Radio Shack
hardware is compatible with the CoCo
3. Is there any way I can fix the RS-232
pack? It will not lock up after the first
cold start.
Daryl Fortney
Lancaster, PA
ID The CoCo 3 will run many CoCo
jC 2 programs, but not all. Accord-
ing to Tandy, all programs will run "if
they follow the rules," but. unfortu-
nately, not even Tandy itself has fol-
lowed the rules (e.g., the recently re-
leased ROM pack Cyrus is not CoCo 3
compatible). June's column contained a
program, UNDO.BAS, that will aid in
running some, but not all, CoCo 2
software on the CoCo 3. The best way
to use your RS-232 pack with the CoCo
3 is with a Multi-Pak interface (up-
graded for CoCo 3 use) and a real
terminal program with 80-column sup-
port and Xmodem upload/download
protocol.
Directory Printing
Q / have a CoCo 2 and a DMP-110

/£ modifying the machine language
program that is accessed when you type
DIR to use device -2 (Note: 25G-

require either intercepting the CHROUT
vector with a machine language routine
or writing a routine from scratch using
disk I/O to read the sectors containing
the disk directory directly.

Boolean algebra is involved here, but I
cannot figure out how and why it works,
or why it works with the numbers 31
and 63 but not with 9 or 29. It counts
from to 31 over and over, but with
another number it Just counts to I or
not at all. Can you shed some light on
this for me?

D Thirty-one is the equivalent of the
r X binary number 0001 1 1 i I, and 63
is the equivalent of the binary number
001 1 1 1 1 1. If you AND a number with 63,
the net effect is that you get the re-
mainder that would result from dividing
63 into that number. The same is true
for any integer number that has its
binary equivalent of all consecutive Is
to the left of the decimal point. Now, 9
is the equivalent of 00000 100 1, and 29
is the equivalent of 0001 1 101 and con-
sequently, with them, the above is not
true. For a more complete description
of why these conclusions hold, it would
be necessary to go into a long treatise
on Boolean algebra.

How Much Memory?
I own a Color Computer, extended,
with dual disk drive. I also have the
older model Multi-Pak, the Color
File cartridge, and Color Profile. /
cannot get Color Profile to work even
though there seems to be nothing wrong
with it. There is no one in this area
qualified to give instructions on it. The
Color File cartridge works fine, with
one exception. I cannot default the
baud rate to the printer, hence it is
extremely slow. Can the C0C0 2 be
upgraded to 128 K? Is there a program
that would allow me to put the Color
File cartridge onto disk and also enable
me to default the baud? I have an
address list of approximately 340
names and my 64 K cannot handle it
on one tape, so I have to load half
at a time and print them before I can
load the second half. I need the extra
memory to handle the entire list at
one time. I purchased the C0C0 3
because it has I28K only to find that
all I have available is what I now
have in my Extended BASIC C0C0.

D Your Color Profile disk should
pC work just fine. If you are having
problems with the disk, you should
contact the Radio Shack from which
you purchased the program. Now, in
answer to your other questions, you
can obtain memory upgrades to
128K, or even 512K, for the C0C0 1
and 2; however, this memory would
not be used in the C0C0 as contig-
uous memory. As a result, it would
not be used by commercial software,
such as Color File or Color Profile,
for data storage. In most cases, these
upgrades are designed with the
hacker in mind or for use as a RAM
disk or print spooler. For your pur-
poses, the best solution would be to
use the C0C0 3 with OS-9 Level II
and an OS-9 database program.

Powerful New Utilities
for the CoCo 3
How many of you have bought a new utility program for
your CoCo to find out that it was too much trouble to look
up the loading address or figure out the offset, or, no matter
what, the miserable thing crashed your computer if you
sneezed at the wrong time? 1 know that it's happened to me
more times than I want to remember. Bangert Software
Systems has four utilities for the CoCo 3 that will not
become dusty, never used relics. They work, they do what
they're supposed to do, and they recover from a reset intact.
The system requirements are a CoCo 3, one disk drive,
either. RGB or composite monitor, or a TV, and a printer
for two of the four programs. They can be copied to one
disk so you have almost the equivalent of an OS-9 startup
file or an MS-DOS batch file.
Each utility is supplied on a separate disk, not copy-
protected, along with the assembly language source code,
a special file called SPAEXIT.BIN (which is called by
pressing the reset key and leaves with all utilities still intact),
and a whole barrel full of other supporting files that allow
the user to list the full manual to the screen and send it to
the printer, BASIC loader programs for each utility, and a
master loader for all of them.
Don't let the assembly language reference scare you. You
don't need it to run any of these routines. It is supplied only
as an extra for those who are interested.
Each utility disk has a program called PRINT. BflS on it
that lets you RUN "PRINT and be prompted as to the
documents you want sent to your printer. You have the
option of entering ALL, and I suggest that be done. Then
you'll have the total manual for all four utilities, and it will
give you an idea of how they interact and whether you want
to purchase the rest of the package. Unless the final edition
has one small bug perfected, you will have to first load
PRINT. BflS and then list Line 40. If the last word in that
line is STARTTYP, you will have to edit Line 40. Change
STARTTYP to STARTYPM. Then type RUN, answer the
prompts, and you can go feed the cat while the manual is
being printed out. Also, when asked for the baud rate for
your printer, just enter the value you're poking, not the
location. That is, for 9600 enter 1, not 150,1.
If you don't have a printer, you may use the LIST program
to read the same information on your screen. This is an
example of the attention to detail Bangert has employed to
make these utilities easy to use.
Print Spooler is probably the most useful of the package.
First of all, you may LLIST a BASIC program to the printer,
and while the printer is churning away, you can continue
to edit the same program, run it, load another program and
run it, or go watch TV. If you have a BASIC word processor,
the document can be printed while you work on another
one, clean up your disk files or write another program.
Formatted LLISTings can be made with a simple poke. If
you're writing a program, a formatted LLIST will make
debugging much simpler. All baud rates are allowed,
whether using a serial or parallel printer.
The spooler is a tad over 1 IK, but will process anything
within the limits of memory.
Directory Dale is another important utility if you have
a lot of files on a lot of disks and tend to lose track of when
files or programs were last updated. It prompts the user to
set the time and date on power up and stamps that
information on all disk saves. That means if you type DIR,
the time and date you saved the file will be shown.
Typ-O-Matic incorporates several functions. The first is
an automatic key repeat, which repeats each key if held
down for a half second. The next is an audible key click,
which means when you press a key, you can hear a soft
thump. Once you use these, you won't want to do without
them. If you have the screen print utility installed, it can
be called from Typ-O-Matic with two keystrokes. The last
feature, and least useful, is an alternate keypad mode. The
author has given 10 keys on the computer a second
definition, which are accessed by pressing the ALT key. This
"They work, they do
what they're
supposed to do, and
they recover from a
reset intact. "
is designed to give you a numeric keypad and hardly seems
worth the trouble, but more creative types than I might
think differently. Incidentally, the 10 keys plus 25 more can
be redefined by the user and saved into a startup file.
Screenprint prints the contents of your Hi-Res text screen
to your printer on command.
There were a few aspects of these utilities that 1 found
troublesome. The auto key repeat works with CTRL and
ALT, which makes the user stop and think before typing a
two-key combination using them. When the ALT key is
depressed to change to the redefined keyboard, an '!' is
generated on the screen. These aren't bugs, only a little
awkward; however, when I called Bangert the author said
he had already corrected these plus the Print program listing
error.
I should mention one other undocumented feature of the
date/ time module. When you first boot your computer, you
are prompted to enter the time and date. The program asks
for MMDD; that is. May 1 would be entered 0501, with
no provision for the year. It will accept five digits, so you
can enter 05017 for May 1, 1987. Actually, you can enter
the full year until October rolls around, because the leading
zero is ignored.
This is an excellent package. It's user-friendly and easy
to install; it can be customized to your system, thanks to
the examples and the BASIC loaders, and also provides all
the assembly language source code. In my opinion the key
click, key repeat, print spooler and date/ time routines are
worth the price by themselves.
I also congratulate Bangert for publishing a program(s)
that requires only six or seven commands to remember,
operates transparently, uses only 112 bytes of BASIC
memory, and pays attention to both the beginner and
advanced user.

Satisfy Your Appetite for
Action With Donut Dilemma
NovaSoft has added a new program, Donut Dilemma,
to their list of excellent arcade games. The documentation
is covered on two pages. As in most arcade games, you do
not need much in the way of instructions; all you really need
is experience. The documentation also includes a good
description of the arcade scenario.
Angry Angelo has raided Antonio's Donut Factory
sending everything into disarray. Donuts have come alive.
They are jumping around in a wild frenzy and are deadly
to the touch. Machines have gone out of control, throwing
cooking fat, dough and icing sugar everywhere. All these
can also be fatal to Antonio. Your job is to help Antonio
climb ladders, jump platforms and ride elevators to reach
the top floor and shut down the factory's power generator.
For each floor level (except Floor 10), you must get to the
small elevator platform that takes you up through the
ceiling and into the next floor level. Unfortunately, due to
circumstances beyond anyone's control, the three circuit
breakers on each floor that activate the elevators have been
switched off. You must, therefore, activate all three circuit
breakers to activate the elevator for that floor. Bouncing
donuts will be in your way. The only way to get past them
is to pop them by throwing a handful of dough mix at them.
"Your ultimate goal is to
reach Floor 10 and
deactivate the power
generator to restore law
and order in Antonio's
Donut Factory. "
To get some dough mix, you must first get the blue bag.
You see. each floor has a blue bag that contains five handfuls
of dough. Your ultimate goal is to reach Floor 10 and
deactivate the power generator to restore law and order in
Antonio's Donut Factory. Besides having to work against
all these obstacles, you also have to work against the clock.
If you do get into trouble, or rather, when you get into deep
trouble, there is a panic button available that you can use
once during each game. This refills your dough bag and
temporarily stalls the timer.
When you first start a game, you have the option of
playing a practice game. This is a very nice feature because,
otherwise, 1 would have never seen all 10 floors. The practice
game is just like a regular game except there is no scoring
and you have unlimited lives. This is where you can get all
the practice you want on each level. You do have to start
from the bottom, though; you cannot just pick the level or
floor you want. The instructions state that Floor 9 is not
impossible; it just needs a lot of thought. 1 can agree and
add, it takes some good timing. Once you think you have
had enough practice, exit the practice mode and see how
good you are on the regular game.

Custom Palette Designer
Makes Color-Handling a
Breeze
I have been involved with the TRS-80 world since 1977
when I bought a 4K Level I, Model 1 computer. 1 have
always been interested in graphics and love the way they've
developed. 1 am always interested in programs that make
graphics or color-handling easier, and the Custom Palette
Designer Version 1.0 makes palette color manipulation a
breeze. This well-written program requires a I28K. CoCo
3 using either 1.0 or 1.1 Disk BASIC, and at least one disk
drive. The Custom Palette Designer allows you to change
any palette slot to any other color you desire — without
having to remember names or numbers of colors. The
program modifies any or all of the 16 slots (0-15) to any
of the 64 colors available on the CoCo 3.
After loading the program, you are asked if you are using
the RGB monitor or not, and then you are presented with
the main screen, which shows the 16 default palette slots
and a pointer beneath Slot 0. Altering the color contents
of the palette slots is easy and handled with the arrow keys.
The up and down arrows move the pointer either forward
or backward one slot at a time, and the left and right arrows
change the color of the palette.

The Custom Palette Designer also makes use of the
additional keys on the CoCo 3 keyboard.The Fl key resets
the foreground color to white; F2 resets the background
color to black; and the ALT key resets all the palettes back
to the default colors. This is especially helpful if you make
an error and need to start all over again with a clean slate.
After you have the palette slots the color you want them,
you have the option of saving the configured palettes to disk
as an ASCII file with the line numbers of your choice so
you can use the files as a subroutine.

The power of this program is obvious. If you'd like to
give your BASIC CoCo 3 programs a different look, and you
use the PALETTE command a lot but don't want to be
bothered with changing the color manually each time you
run it, create several alternate palette subroutines, merge
them into the BASIC program you're using, and, presto,
different colors!
The Custom Palette Designer has a place in the library
of the BASIC programmer. The manual is small but easy to
use, and the software can be a great timesaver.

Hint . . .
Useful Commands
for Controlling Graphics
Most people, when writing graphics programs for
the CoCo, use an infinite loop (e.g., 1000 GOTO 1000)
to make the graphics stay on the screen. In many cases,
it is better to use the LINE INPUT or INKEYS com-
mands. These commands allow you to enter a line of
text or just a single keystroke, which the program can
interpret, transferring control to the appropriate line.
This is especially useful if you want to graph functions
and you want to see several different values graphed.

Basic Freedom Eases
Programming in BASIC
BASIC on the CoCo is a powerful tool. It has easy to use
commands to generate graphics and sound, and manipulate
text and numbers, and it can access both random and
sequential files on disk. Even with all this power, however,
we often find ourselves wanting "just one more feature" out
of BASIC. Many of those people's wishes have now been
granted: Dr. Preble's Programs has just introduced Basic
Freedom, a utility to add several new features to BASIC and
simplify its use for programmers.
Basic Freedom is a full screen editor for either the original
CoCo 1 or 2 or the new CoCo 3. It works in the 32-column
mode, or the 40- or 80-column mode on the CoCo 3. In
addition, Basic Freedom modified basic so that lowercase
commands can be executed, added the ability to repeat any
key just by holding it down, and makes the LIST command
more powerful. All of this is done without losing any of
BASIC'S memory as Basic Freedom resides in high memory.
Basic Freedom comes on a non-protected disk for both
the CoCo 3 and the original CoCo and on cassette only for
the CoCo I or 2. It requires 64K on the original CoCo or
128K on the CoCo 3. In addition to the cassette or disk,
Basic Freedom includes a six-page manual. The manual is
well-written, clear and easy to understand.
Loading Basic Freedom couldn't be simpler. For those
with the DOS command, simply put the disk that the
program comes on in Drive and type DDS. For those
without a DOS command, simply type RUN "*". The cassette
version is loaded with a simple CLOADN statement. Once the
program loads, it is ready to use.
To use Basic Freedom's full screen editor, you type EDIT
DN. On the CoCo 3, you can use the F2 key as a shortcut
to turn the full screen edit mode on. Once you have the edit
mode on. you can move the cursor anywhere on the screen
with the arrow keys and edit the text on the screen with the
ease of a word processor. After you edit a line of text, you
move the cursor to the end of the line and press ENTER. The
line is now entered into the computer with the changes you
just made. While full screen editing, you may move the

cursor, delete characters and insert characters. You can
always tell when the editor is on by looking at your cursor.
In the 40- or 80-column modes, it is solid instead of blinking
when the editor is on. In the 32-column mode, the cursor
blinks a single color when the editor is on.
In addition to the full screen editor and the lowercase
interpreter. Basic Freedom also provides a more powerful
LIST command. In addition to the normal LIST functions,
you can list a number of lines past a line number, such as
the next five lines after Line 40, you can add a semicolon
to the end of a line to execute a command after the LIST
is over, and you can add a comma to a LIST command to
list another set of lines after the ones you list. As an example:
LIST 10-20, 50!B, 90, 100-:EDIT ON
This command would list lines 10 through 20, eight lines
starting at Line 50, Line 90, Line 100 to the end of the
program and would then turn on the full screen editor.
All these features add up to a program that makes
programming in BASIC much easier and faster. If you do a
lot of programming in BASIC, you will like this program.
The bottom line is that this is a utility. You can use your
CoCo without it, but it is much easier to program in BASIC
with it. Is the added ease worth the price? Yes, the price is
worth what you get and is in line with the rest of the market.

Koronis Rift Lets You
f Shoot 'era up' and a
Whole Lot More
By Donald D. Dollberg
With the introduction of the Level II OS-9 operating
system for the Color Computer 3, Tandy is now releasing
several games that use this operating system. The latest
game, Koronis Rift, is distributed by Tandy but was
developed by Lucasfilm Games and Epyx. It will only run
on a CoCo 3 and requires OS-9 Level II.
As has been Tandy's practice in the past, the OS-9 boot
is on the game disk, so those not having OS-9 do not need
to purchase it separately. The game is booted by typing DOS.
For those with Disk Extended BASIC 2.0, you will need to
type a short BASIC program, provided in the documentation,
which performs the function of the DOS command. Upon
initial loading of the game, you will be prompted as to the
type of screen device available, i.e., composite or RGB
monitor. Selection of the composite monitor allows viewing
on a TV. Also, one joystick is required.

Rift"! Since one of the developers is Lucasfilms, of Star Wars
fame, you should have guessed that this is another space
Adventure. Well, you're partially correct. This is not an
Adventure game as most of us know them, nor is it a
continuous "shoot-'em-up" game, although you do get a
chance every now and then to shoot down the aliens.
The premise of the game is simple. You are a techno-
scavenger or, in simple terms, a businessman trying to make
a buck. In your trusty scoutcraft, you have come across the
legendary planet Koronis, which is a high-tech graveyard
of the Ancients — a confederation of over 30 different races
who ruled the universe several hundred thousand years ago.
The Ancients developed a technology that, even today, is
unsurpassed.
Legend has it that the Ancients used the planet Koronis
for testing their technology. Because of the deep rifts on
Koronis, it was an ideal testing ground for powerful
weapons. Until now, no one has ever found the "fabled"
planet Koronis — and there it is on the view screen of your
scoutcraft!
You immediately put your ship into an orbit around
Koronis and prepare to scavenge the planet for as much
equipment as possible. With an advanced Psytek series
computer in control of the scoutcraft, you beam down to
the surface in a surface rover. When you land on Koronis,
your radiation alarms sound, confirming the rumors that
lethal radiation exists on Koronis. Luckily, your surface
rover is equipped with a repo-tech robot that does the actual
salvage operations once you find one of the Ancients' hulks,
which house their high-tech equipment. Using the special-
ized radar in the scoutcraft, you guide the vehicle toward
the first hulk with the joystick.
With all of the technical capability available to you in
the scoutcraft, this operation should be a "piece of cake,"
but is it? As you move along the rifts, you suddenly
remember the other half of the Koronis legend. The hulks
are protected by the Guardians, a race of genetically-
engineered warriors created by the Ancients. The Guardians
were programmed by the Ancients to guard and defend their
military stockpiles and have steadfastly refused to negotiate
with anyone.
As you approach the first hulk on Rift l , you are thinking
of the long and dangerous task ahead. The profits are
enormous and you can quit at any time. However, while
collecting equipment from the Ancients' hulks, be careful
that the Guardian saucers don't destroy you first. As you
136
THE RAINBOW August 1987
move from Rift 1 to Rift 20, you are able to make use of
some of the equipment collected. You can also dismantle
the equipment and eventually sell it for profit. If you make
it to Rift 20, the Guardian base must be destroyed before
you can claim the entire planet as your own.
Just what type of high-tech equipment will you find on
Koronis and what do you do with it? The standard military
systems that the Ancients used include chromoquantized
lasers, which are capable of emiting a beam in a single color
frequency; chromoquantized shields, which can defend
against the lasers; standard power supply generators; high
capacity energy storage devices; remote sensing devices,
which are designed to locate specific types of hardware;
electronic countermeasure devices, which are capable of
interfering with enemy detection gear (making it difficult
for the Guardians to find you); and propulsion modules,
which can augment the power drive for the rover for
different types of terrain.
As noted earlier, the Ancients were a Confederation of
many races. Each race built its own version of military
hardware, which was standardized throughout the Confed-
eration. Since the races were not of equal intelligence, the
same type of military hardware will have greater or lesser
capability. As you travel around Koronis, you find some
equipment to be more power-efficient, as well as more
effective. So, you need to evaluate each item taken from the
hulks and decide whether to put it into service in the rover
or have it dismantled and sold for scrap.
At any time during the game, except when under attack,
you can beam up to your orbiting scoutcraft. Once on
board, you can have the Psytek 7500 Series Science Droid
System analyze the equipment and install it in the rover to
a maximum of six units or store the excess equipment in
the scoutcraft's storage area. Equipment in storage can
either be used later in the rover or you can have Psytek
dismantle it for sale — which is how you make money, i.e.,
points, and eventually win the game.
Deciding which equipment modules to keep and which
to dismantle is an important part of the game. Each module
uses up a certain percentage of the rover's power supply and
also has an efficiency percentage. The better modules use
less power and are more efficient. They are found by in-
depth searching, as you move from one rift to the next. As
modules are found, they must be analyzed. Psytek will
perform the analysis and tell you the power usage,
efficiency, and how many points will be earned for
dismantling each module.
Some modules, when combined in the rover, provide even
greater capability. For example, the generator and power
reserve modules are needed to maintain a good power flow
for all of the other modules and the rover's functions. Use
of modules with high power requirements slow the rover's
speed and may prevent you from firing your lasers at the
Guardians.
You begin the game with a laser and a shield. As you fill
the rover's cargo area, you must keep in mind the obvious
fact that you will need a laser, shield, generator and maybe
a power reserve. With the more powerful lasers, you also
need better power sources because they require time to
recharge. Also, the high power lasers cannot be fired
continuously, so if you don't have a good aim you may be
frustrated waiting for your next chance to shoot.
Lasers and shields operate at different wavelengths or
colors of the spectrum. The rover has a monitor that
displays a horizontal bar graph showing the strength of the
current shield in use. Six color bands are present; the length
of the bar indicates how much protection your shield will
give against a laser of that wavelength. Better shields give
equal protection against all wavelengths. Some shields
provide excellent protection against a few wavelengths and
poor protection against the remaining wavelengths. This is
"Overall, I liked this game
and enjoyed it very much.
The graphics are very well
done, with fine detail given
to the Psytek computer
system and the hulks on the
planet. The animation is
realistic and gives the
viewer the feeling of
moving up and down over
the hilly terrain of the planet. "
good only if you know the color frequency of the alien's
laser. The laser module works in the same way, but only
fires at one wavelength.
The best laser is the one that is farthest away from the
alien's color in the spectrum. On another monitor in the
rover, you can find information on your current laser's
operation. A vertical graph displays two bars. The left bar
shows the color and amount of power available for the laser,
and the right bar shows the amount of power needed to fire.
The left bar decreases with each shot so the laser can only
be fired after it recharges to the power level indicated by
the right bar. If there is no right bar, then you can fire almost
continuously. The laser recharges better when there is a
good power reserve module, but the power reserve module
needs a good generator too.
The documentation provided with the game is well-
written and interesting. Even more interesting is the fact that
the documentation never mentions the CoCo 3 but explains
how to load the game into an Atari or Commodore
computer! A separate instruction card provides directions
on use with the CoCo 3. It appears that Tandy had Epyx
port the game from these computers to the CoCo 3. This
is a good sign. Since the CoCo 3 graphics screens are very
similar to these machines, we should see more porting of
software to the CoCo.
Overall, I liked this game and enjoyed it very much. The
graphics are very well done, with fine detail given to the
Psytek computer system and the hulks on the planet. The
animation is realistic and gives the viewer the feeling of
moving up and down over the hilly terrain of the planet.
Koronis Rifi is not a constant "shoot the aliens" game and
does require the evaluation of the equipment you find so
that you can make it to Rift 20. For those who like this type
of game, I recommend that you start your salvage opera-
tions as soon as possible, and, "May the Force be with you."

Color Scripsit II Provides
Power and Simplicity
Radio Shack has a new word processing program. Color
Scripsit II, for the original CoCo and the Color Computer
3. It comes on a cartridge and has no provision for disk use
— all files are saved to, and loaded from, tape.
"Word processing," according to the introduction in the
manual, "does for your writing what the automobile did for
transportation. It provides you with a powerful new tool
not available formerly to individuals." Color Scripsit II is
aimed at the computer novice. While VIP Writer, for
example, emphasizes its powerful features. CS II points to
its simplicity. "Simply insert the Program Pak and turn on
your computer. Select an activity from the Main Menu, and
return to the Main Menu when the operation is finished."
That is not to say that CS II lacks sophistication. It
certainly stands head and shoulders above the original
cartridge Scripsit, which, it may be recalled, did not even
permit varying the baud rate from the Radio Shack
standard of 600. The new program (not a revised version
of the original by any means, but a totally new program)
not only permits you to select the baud rate, but also to
"tune" it, if your printer happens to require such a thing.
And, unlike its predecessor, CS II produces ASCII-
compatible text files, yet can read files created by the old
Scripsit.
Like most other word processors, CS II permits format-
ting, global search and replace, right-justification, block
moving, block copying, block deleting, centering, headers
and footers, page numbering, underlining and printer
control codes.
CS //does not have wide, high-resolution display screens.
A 38-by-24 screen, genuine lowercase characters and a
variety of foreground/ background color choices are
available on the Color Computer 3. With the CoCo 1 or
2, you can have any display you want, as long as you want
the basic 32-by-16 black on green.
The eight menu options are: Edit, View/ Format, Print,
Unformatted Print, Load from Tape, Append from Tape,
Save to Tape and Skip Tape File. Edit is where you go to
write and make changes in your text. Unformatted Print
prints a hard copy of your text file with format command
lines treated as though they were printable text instead of
commands. Skip Tape File is the equivalent of BASIC'S
SKIPF command. It advances the tape to the start of the
next file, while displaying the title of the file that's being
bypassed.
Edit has two subsidiaries — command mode and insert
mode. When you press E for Edit from the main menu, you
are placed in command mode. Before you can start writing,
you must get into insert mode. In insert mode, all you can
do is write (and backspace with a destructive cursor). To
do anything else, you must break out of insert mode, move
the cursor to the appropriate point, and then insert or
"replace" as required.
Personally, I found all this mode-switching a bit annoy-
ing, but maybe that's because I'm used to a word processor
that does things differently. Also, the screen and the cursor
look exactly the same in the two modes. A slight variation
would have been helpful.
The view mode displays the current page of your
document as it would appear if it were a printed page. What
you see are not the actual characters — they would be too
small to be legible — but a depiction of the location of
characters and spaces on the page.
What you get is a rectangle with blocks and dashes that
show you how the paragraphs will be arranged on the page.
1 would have liked this much better if the screen background
had been white instead of green. Along with the blocks and
dashes, you get a cursor (represented by a cross), which you
move with the arrows until it's over the paragraph you want
to format. Then you enter the format mode, where you
make your formatting selections by answering the onscreen
prompts. Each selection generates a format command line,
which is inserted into the textfile. As an alternative, you may
type your format command lines manually, in the same way
that you type in text.
Perhaps the best feature of CS //is its instruction manual.
It has 63 pages — but its size is only 4-by-4!/> inches. It
makes learning CS II easy for those who have never used
a word processor.
As good as it is, however, the manual is not without its
faults. It lacks an index, and one important feature called
Fill is explained inadequately.
The underlining and other formatting features are
command lines, preceded and followed by carriage returns,
and they apply to subsequent paragraphs until amended by
subsequent format command lines. But suppose you want
to underline only a single word in a line, as I have just done.
That's where Fill comes in. You must type the word to
be underlined as though it were a separate paragraph and
then use fill to join the separate paragraphs into a single
line. I had a lot of trouble figuring out how to get it to work
right, finally discovering by trial and error that any line to
be joined to a subsequent one must have no space preceding
its carriage return and that the No Fill command must
precede rather than follow the last line to be filled.
Color Scripsit II requires a minimum of 16K. On a 64K
CoCo, the text buffer will hold 47,607 characters.

Hint .
A Passel of Pokes
When you ask your CoCo to print a number, it
prints your number with a leading blank space if it
is positive and with a minus sign if it is negative. To
eliminate the sign altogether, enter POKE
S.HBDE4,1B:P0KE &HBDE5,1B. Please note this will
also remove the minus signs! To restore your CoCo
so that it includes the sign, enter POKE
8.HBDE4,&HA7:P0KE &HBDE5,&HC0.
If you want a plus sign instead of the blank space
for positive numbers, enter POKE &HBDDD.8.H2B. To
restore your CoCo, enter POKE $HBDDD,&H20. All of
these pokes work with the CoCo 1, 2 and 3.

Super Extended Basic
Unravelled for the CoCo 3
Super Extended Basic Unravelled is a bound, soft-cover,
magazine-sized book that details everything you want to
know about the super high resolution graphics commands
and basic enhancements on the Color Computer 3. It
provides the reader with a complete and detailed, fully
commented source listing of the super high resolution
graphics packages available on the CoCo 3 with Color
basic 2.0 ROM.
The book is not a tutorial or a how-to manual, but rather,
a comprehensive source of the assembly listings. The reader
needs to have at least a basic knowledge of 6809 assembly
language programming to be able to take full advantage of
the opportunities that the book offers.
The subject matter includes CoCo 3 hardware differences,
memory management, super Hi-Res graphics, colors and
palettes, interrupts, and Super Extended BASIC.
This book is loaded with useful information for the
serious CoCo 3 hacker. 1 believe that the information
supplied is well worth the price; in fact, the disassembled
listing of Super Extended BASIC 2.0 is worth the price of
the whole book.

Magnavox RGB Monitor 80
Provides Plenty of Resolution
and an Excellent Display
The Color Computer 3's analog RGB output certainly
provides very nice pictures, but it does have its limitations
- not the least of which is its inability to display the PM0DE
A artifact colors used by many existing CoCo programs. The
fact that the RGB colors are vastly different from those seen
on TV sets or composite monitors (a problem only partly
dealt with by the PALETTE CMP and RGB commands) doesn't
help matters, especially for those who want to write
programs designed to work with both types. One way to
get around this is to use both an RGB monitor and a
composite monitor or TV set, but this can get clumsy (not
to mention the expense of buying two monitors, if that's
what you need to do). Another is to use a single monitor
that can switch between RGB and composite video, and the
Magnavox Professional RGB Monitor 80 (model 8CM515)
is one of the better ones. (I should note here that Magnavox
also sells a similar monitor, model 8CM505, which is called
the RGB Monitor 40; it uses a less expensive picture tube
that delivers somewhat less resolution. This review deals
strictly with the8CM5l5.)
Don't let the Magnavox name fool you; the RGB Monitor
80 was designed and built by Philips, the European electrical
giant that bought out the Magnavox TV and audio
businesses some years back. Philips has a fine reputation
for quality and innovation, and their skill shows in the
design of the RGB Monitor 80.
The Magnavox monitor doesn't look particularly
unusual; it's about the same size as most RGB monitors,
and its off-white color matches the CoCo case nicely. All
the controls except for the power switch are concealed
behind a flip-down cover below the screen. The monitor has
a tilt stand that drops down from the front edge to prop
it up to a good viewing angle.
In the RGB analog mode, the RGB Monitor 80 gives a
very nice display; all the CoCo 3 colors are displayed well,
and the fine-pitch screen gives plenty of resolution for
displaying 80-column text. The picture tube has both a
140
THE RAINBOW August 1987
tinted faceplate for higher contrast (though not quite as high
as some other monitors and TV sets), and this has been
treated with an anti-reflective surface that helps reduce
reflected glare to a great degree. Although some monitors
(such as the Sony KV-1311CR or the NEC MultiSync) do
provide even better resolution, it's hard to find fault with
the Magnavox display.
Composite color performance is quite decent as well,
though with a few minor defects. The composite picture is
just a bit less sharp than what I'm used to seeing, probably
due to the low-pass filter used to keep the color subcarrier
signal from appearing in the picture when the comb filter
is switched out. (The comb filter circuit used by Magnavox,
unlike that used by RCA and some others, has some
unfortunate side effects on the picture in some situations;
the RGB Monitor 80 has a switch to disable the comb filter,
and for CoCo use it should be switched out.) Despite this,
the Magnavox monitor provides reasonably good results on
the CoCo composite video output, and when I used it to
watch regular TV programs (feeding the video output of my
VCR into the monitor), the pictures were very good with
pleasing color fidelity. (I even tried watching a newscast
from London, received by satellite, which was transmitted
using the European PAL system; the Magnavox monitor
automatically switched over to the "foreign" 50 Hz scan
rate, although 1 got a black-and-white picture because the
monitor was built for the U.S. NTSC system.)
The RGB Monitor 80 can also be used to display the
"TTL RGBI" output of a PC-compatible computer such as
the Tandy 1000; since this is only a secondary consideration
to most rainbow readers, I'll simply say that this worked
every bit as well as did the analog RGB mode. The
Magnavox monitor has a "green only" switch to give you
the equivalent of a green-phosphor monitor.
To sum up, I would definitely recommend the RGB
Monitor 80 to anyone who has a CoCo 3; it gives an
excellent analog RGB display and, even if you don't need
the composite video mode, it's one of the better monitors
on the market.

Develop Programming Skills
With CoCo HI Utilities
CoCo III Utilities is a set of nine programs on disk that
can be used for practical applications with many of the new
features on the CoCo 3.
MEMTEST is a 128/512K memory test program.
The new high resolution screen uses 32K of memory and
is not part of your BASIC program. This means that while
your BASIC program no longer is limited because of
graphics, you cannot directly save the screen to tape or disk.
The LOADSAVE routine solves this problem.
VERSCROL is a utility that demonstrates how to smooth
scroll vertically using the joystick; and HORSCROL, a
horizontal direction.
CH ARPOKE lets you change the attributes of individual
text characters such as blink, underline, color and back-
ground, as well as the number of screen columns.
CC3WORD is a simple, single-screen, word processor
with which you can fill the screen with text. You can even
save it and print it, but its intent is to demonstrate how to
effectively use the 40- and 80-column text modes.
CC2TOCC3 converts graphics and text to CoCo 3
format. This utility assists in making this conversion,
although it won't take care of everything and only works
on disk.
CIRCLES is a palette registers demo. This utility lets you
display your choice of 64 different colors, 16 at a time, on

Gridiron Strategy
Scores a Touchdown
For all you CoCo nuts who are football fans, SPORTS-
ware has come out with a Hi-Res football game that will
ease the withdrawal pains that come with the Super Bowl
each season.
Gridiron comes in an attractive, hard-cover folder with
program disk (not copy-protected), two Offense/ Defense
cards, two Defense selectors, and an 11-page manual.
System requirements are a CoCo 3, one disk drive and a
color monitor. 1 tried it on both RGB and composite color
monitors. The graphics were great on the RGB and fair on
composite. The author said he intends to put an RGB or
composite option in the release version.
The manual is well-organized and well-written and will
probably be needed only about 10 minutes, as the gamejust
about runs itself. The only criticism of any importance is
that it doesn't stress, or even mention for that matter, the
importance of backing up the program disk.
The game is written in machine language so after a LORDM
and EXEC, it takes about 30 seconds to load and give you
the game screen. This consists of a scoreboard at the top,
showing the team names, timeouts remaining, score,
quarter, down, yards to go for a first down, yardline the
ball is on, and time left in quarter.
"With more than 20
offensive plays and 10
defensive plays, there are
200-plus possibilities. "
In the center of the screen is an overhead view of the
football field, and on the bottom is an information window
that shows the last offensive and defensive plays used and
tells how much the play gained or lost. There is also a
message window that comes down over the field itself that
asks for prompts, tells you when you made a touchdown,
scored an extra point or had a pass intercepted.
You are first given the opportunity to change the name
of the teams; next, to change the default time (15 minutes)
of a quarter. This is all prompted by the program and, again,
almost runs itself. Next, you get to call the coin flip to see
who kicks and who receives. This was the only bug 1 could
find in this program; it always came up "heads"! The author
says this has been fixed.
Once the preliminaries are over, the kicking team is given
the choice of a regular or onside kick. The computer does
a simulated dice roll (shown graphically and based on
football statistics) and you have the field in front of you
with the ball marked, the 10-yard marker on your screen
in your team color, and a drive marker that extends if you
have a sustained march.
Now the competition begins. Each player has a card with
offensive plays on one side and defensive plays on the other.
Each selects what he feels appropriate to the situation. The
defensive player must signal — via a defense-ready marker
— that the offense can enter his play in the computer. The
defense then enters the play he has picked as shown when
he turns his marker over. Neither team knows what the other
one is going to do ahead of time.
The computer moves the ball marker, changes the down,
changes the yards to go for first down, changes the clock,
and changes the possession if it was a fourth-down attempt.
At the end of each half, you are given a two-minute
warning. You are also given a screen print of halftime and
end game statistics, the latter after the fourth quarter.
3 BRONCOS
:
Quarter 1 Time £ :(
Down 1st To 90 19 Ball on 45
Last play: Gain of 0=/ D = *
Enter Offense
The heart of the strategy are the play cards. Each card
has 20 offensive plays plus punt and field goal on one side
and 10 defensive plays on the other. The offensive plays are
diagramed, categorized by runs, short passes, medium
passes and long passes. They are also grouped to show
average gain per play. The defensive alignments are just as
thoroughly documented. Each defense is rated for its
success against the type of play anticipated. This sounds
complicated, but isn't.
There is very little randomness in this game. That is to
say, if you run up the middle against a defense that's set
to stop a run up the middle, you aren't going to gain much
yardage. But the important thing to keep in mind is that
with more than 20 offensive plays and 10 defensive plays,
there are 200-plus possibilities. There are also penalties,
interceptions and timeouts that give this game a real football
feel.
This is not a shool-'em-up, fast fingers, joystick-type
game. The program waits for the players rather than the
other way around. There are sound effects, but they do not
slow the play. The error protection is flawless. Good use is
made of the CoCo 3's graphics. The game is not played in
real time, but the author has done a clever job of accounting
for time and timeouts.
In summary, this is an excellent game. After three weeks
with it, I still find it fascinating. If you have your CoCo 3
connected to an old TV or composite color monitor with
a bad picture, I would stay away from it, unless the issue
version has a menu option for RGB or composite. Other
than that, 1 give Gridiron a very high recommendation.

Tap Into Better Graphics
on Your CoCo 3
A Second Look at
Telewriter-64 and Friends
Most would agree that one of the most important aspects
of the Color Computer 3 is its enhanced graphics capabil-
ities. Now, Moreton Bay has introduced Better Graphics on
Your CoCo 3, a book designed to let you tap into these
wonderful graphics abilities.
Better Graphics on Your CoCo 3, or Belter Graphics for
short, is a 43-page, staple-bound manual chock full of
information nearly anyone can use as they learn about their
new machine. It offers five major sections, each detailing
certain aspects of graphics operation on the CoCo 3.
The first section, Memory Organization and Manage-
ment, discusses at some length just how memory is allotted
in the Color Computer 3. It is good to see that the author,
Linda Nielsen, chose to discuss such an important subject
first. Manipulation of graphics does require a working
knowledge of memory organization.
The second section offers some information about the
binary number system and discusses how graphics memory
is translated into a usable onscreen image. It also gives
detailed information on the assorted graphics modes
available on the CoCo 3.
The third section of Better Graphics shows the reader how
to use the various graphics modes and also how to create
text on the high resolution screens. This section, along with
the first section, would be suggested reading for any CoCo
3 owner.
The fourth section covers animation and scrolling
techniques, while the fifth section pulls everything out of
the hat and gives you detailed information on using your
CoCo 3 in ways BASIC never heard of.
Now, lest you think you might have to type in numerous
examples, Moreton Bay includes two disks with all
programs on them. In my opinion, this complete package
approach really enhances the educational value of Better
Graphics. After all, if you have to spend your time typing
in example programs, it can be quite difficult to follow and
comprehend the principles the book is trying to teach.
Certain parts of the book may be more than some people
can understand. The book is intended for those people who
want to program, especially with graphics. However, the
book takes the chore out of understanding graphics and
memory utilization on the CoCo 3. With few minor
exceptions, all points are clearly presented and anyone with
a basic working knowledge of Color Computer program-
ming should be able to follow it with little or no problem.
Better Graphics on Your CoCo 3 should be a part of
everyone's library.

(This program [June 1 983 J and its patches have been
reviewed in previous issues of THE RAINBOW, but we're
taking this "second look "for the benefit of new readers.)
I remember about 10 years ago when I first heard the term
"word processor." At first it seemed odd that anyone would
want to use a computer to write letters, articles or reports
instead of a typewriter. But the more 1 read of and watched
this new writing technique, the more its many advantages
became obvious.
The rest is history. Just about everyone has some idea of
what a word processor does even if they have never used
one. This is due largely to the computer revolution that we
are all participating in, as well as the vast usage of word
processing in the work place.
For those of you new to the CoCo community who want
to use your computer for some serious applications, you

should consider word processing in general and Telewriter-
64 in particular. I suggest TW-64 not only because I use it,
but also because of the obvious popularity I see in the many
submissions to THE RAINBOW prepared with TW-64.
TW-64 comes in either disk or tape versions and will run
on any CoCo with as little as I6K of RAM. Since it
automatically configures itself to your computer's memory
size, your text buffer will grow as you add memory. (By the
way, it runs fine on the CoCo 3.)
The user can select any one of three different screen
formats. The screen "wakes up" in the standard 5 1 -column
by 24-line mode, but 64-by-24 and 85-by-24 are available,
as well. The 5 1 -column and 64-column are easily read on
a composite monitor or a good quality TV set, but the 85-
column mode is only good to see the overall layout of your
printed page. 1 use the 5 1 -column mode exclusively and
select 65 characters per line when 1 send the text to the
printer. This results in a nice looking letter or other printed
text.
The user's manual that comes with TW-64 is very detailed
and complete in every way, with dozens of examples of what
the various functions do.
Since TW-64 is a screen editor, all of the data or text is
always present and can be scrolled up or down on the screen.
This is done using the arrow keys. If you type a sentence
and make a mistake, you can simply move the cursor to the
mistake and type in the correction. TW-64 is somewhat
different in this regard, in that it defaults to the Insert mode
rather than the Overstrike mode. This means that the key
depressed at the cursor will add the character rather than
replace it.
While this may sound a little confusing, and takes a little
bit of getting used to, I love it. In the Insert mode you will
never lose text by inadvertent keystrokes. Besides, you can
select the Overstrike mode if you prefer with a simple
keystroke.
TW-64 features three menu screens. The first allows you
to select either the Edit mode or a Newfile mode, which
erases your text if selected. A counter keeps track of the
number of words you have typed, as well as the number of
lines. You can also select either cassette or disk I/O as well
as the second Format menu.
The Format menu is used in conjunction with your
printer. Here you can select line spacing, margins, lines per
page, printer baud rate and queue, as well as right justify.
You can even select where you want the page number to
appear at the bottom of the page. Also supported is a
percent print function, which allows you to print just the
part of the text that you select to your printer.
The third menu screen is for disk I/O. This handles all
of the disk read and write functions. It offers the same
options as for cassette I/O, except for the Verify command.
In the disk I/O menu, you can also see the disk directory
files on the screen or send them to your printer. Here you
can also save, kill or rename disk files without having to
go back to BASIC.
TW-64 also supports the use of embedded commands in
your text. This allows you to perform font changes,
underlining, double-strike, etc., if your printer has the
capability. You can also use these codes to flush text to the
left while maintaining pre-defined columns.
There are far more features than space allows me to go
into here, but the ability to align, scroll and copy blocks
of text, and do easy searches for specified words, makes it
a real workhorse of a program. TW-64 is a full-blown word
processor offering virtually all of the features you would
expect to find in a word processor used on far more
expensive machines than the CoCo. It's available for $49.95
on cassette or $59.95 on disk, plus $2 S/ H, from Cognitec,
704 Nob Street, DelMar, CA 92041, or you can order it from
your local Radio Shack Store.
But Wait — There's More
Telepatch II with The Wizard are two fine TW-64
enhancements available from Spectrum Projects. Telepatch
II provides the user with the ability to configure TW-64 so
that the disk I/O is RAM-resident. This is a big improve-
ment, in that the disk I/O is instant since the program does
not have to be accessed from the TW-64 disk. The only
disadvantage to this is that about 4K of text buffer space
is sacrificed. A buffered keyboard is added with Telepatch
II. Since I am not a super fast typist, I never really noticed
that such a buffer was needed, but I did notice that, every
now and then, TW-64 would drop a character during the
Insert mode. This bug has been fixed with Telepatch II. The
new keyboard routine remembers what characters have
been typed regardless of speed.
The main menu of TW-64 with Telepatch II contains
obvious changes, the most notable being that the cassette
I/O functions are no longer visible. They are fully func-
tional, however, should you need to use them. This was done
to reduce screen clutter and confusion with the correspond-
ing disk I/O functions, since Telepatch II will only work
on a disk system. Other features such as auto-key repeat,
key click, visible carriage returns, overstrike mode and disk
drive stepping rate can be configured in the boot program
to the default of your choice.
The Wizard, contained on the Telepatch //disk, is a nicely
done, revised TW-64 character set. While the new characters
only appear on your screen, they are a big improvement.
The new characters are gently curled and incorporate true
descenders. The text is very easy to read and pleasing to
the eye.
Ultra Telepatch, available from Bob van der Poel
Software, is one of the best enhancements available for TW-
64. This ultra version stores the disk I/O in RAM with no
loss of buffer space. Word delete is added, so you can delete
entire words instead of just one character at a time.
The boot program can be tailored to your needs with disk
drive stepping rate, key clicks, on/ off and reset protection.
What I like best about Ultra Telepatch II is that the text
automatically unfolds on the screen as soon as it is read into
the buffer from disk. Ultra Telepatch II needs 64K of RAM
and disk.
Telewriter-64 with Telepatch II and Ultra Telepatch offer
the CoCo user all that will ever be needed for serious word
processing.

THE RAINBOW August 1987
BASIC TRAINING
DRAW Statements:
Getting the Picture
By Joseph Kolar
Rainbow Contributing Editor
This may well be the most difficult
tutorial you will experience in
this column. The DRAW state-
ment, with all its nuances, is what CoCo
employs to create nearly all of its best
graphics. Thus, it is imperative to
understand how to use DRAW. In the
past, we have made many cute pro-
grams using it. In the future, we shall
study it in more detail.
The DRAW statement is difficult to
read and interpret from a listing. It
makes little sense. But, when the M
option is also thrown in for good meas-
ure, program lines make as much sense
to the newcomer as Chinese.
As hard as it is to create a picture with
DRAW, it is infinitely harder to dig into
the program and make corrections and
alterations.
Key in Listing 1. Here are a few
procedural hints to aid you when you
are extracting or injecting new or re-
placement characters into the DRAW
program line.
When you locate the place you intend
to modify, make a notation on scrap
paper of the actual characters in that
area. For example, type LIST 200. If
you are planning to work at the very
beginning of the line, write on the scrap
paper, U3NR3U3R4BR3. Figure out your
expected changes, for instance,
Florida-based Joseph Kolar is a veter-
an writer and programmer who special-
izes in introducing beginners to the
powers of the Color Computer.
U4NR3U2R4, and place them underneath
your first notation. You then make your
changes — in this example, change U3
to U4 and the next U3 to U2. The reason
for using scrap paper is that after you
make the change, the result may be
wrong or disappointing. You will want
to know what your original data was so
that you can restore it, especially if you
have forgotten which data you replaced.
Whenever you are changing some
characters in a program line, take a
moment to insert a blank space in front
of your target area and then insert a
second blank space at the end of the
work area. This way you will be able to
locate your bracketed work area at a
glance, and the included blank spaces
remain harmless. After you are finished,
you can leave the blank spaces in the
program line, except in the unusual case
where you have the maximum number
of characters in a line. You may prefer
to use the semicolon in place of blank
spaces.
Keep in mind that every time you
tinker with a DRAW statement, there is
the danger that you might distort a
segment somewhere down the line. You
will have to be prepared to make further
remedial corrections.
If you use the "continuous line"
method, you will have to adjust the B
option characters/ values. Frequently,
you will be able to make changes in the
length of a straight line segment using
the N option, avoiding the dislocation of
some part of the program.
By "continuous line" method, I mean
that (H,V), the horizontal and vertical
starting location, is determined in the
first DRAW line. It is not computed again,
since no matter how many DRAW lines
are used, they are merely a continuation
of the previous line.
Relocating each succeeding DRAW
program line is a big waste of time.
Finding a new set of (H,V) values, after
having traveled a tortuous route with
perhaps 40 to 150 direction changes, is
boring and time-consuming.
If you have a graph paper sketch to
use as a guide, your job is half-finished.
Otherwise, you may have to create a
copy of the picture by plotting the
information in the DRAW lines onto
graph paper.
I never told you debugging was easy!
(Notice that I have avoided the nasty
word to keep you in a compliant mood.)
Your graph paper rendition will be an
exact reproduction of your program
lines. It will be a great help in planning
modifications. You will find it is so
much easier to make corrections on
graph paper with an eraser than to
execute tentative, time-consuming
changes in the program lines.
To give you an idea how difficult it
is to rip apart DRAW program lines, Line
200 contains the printed legend, F I GURE
1. Suppose I wanted to make the G more
pronounced. How would you locate it
and revise it to make the hook higher
up? Run, then type LIST 200.
First, you must discover the size,
height and width of a letter and the
width of the space between letters. The
August 1987 THE RAINBOW 149
simplest way is to get some graph paper
(or make some homemade graph paper)
and plot it out. Pick some line intersec-
tion on the graph paper and begin: Go
up three units; go right three units and
return three units left; go up three units;
go right four units.
If you drew the lines correctly, an F
appeared. By counting the line lengths,
U3 + U3 = 6 and R4 = 4, we can infer
that most of the letters will be six units
high and four units wide.
BR3 tells us we moved three spaces
right but did not print a visible line. I
call this the invisible line. Therefore, we
can conclude that the space between
letters is generally three units wide.
Now run. The legend doesn't remain
on the screen long. You can hold it by
pressing SHIFT and @ together. What
we expect to do is make the small,
vertical part of G one unit longer to
make it stand out. That part was two
units long. Depending on which way the
two-unit line was drawn (downward or
upward), it is either D2 or U2. Press
BREAK and type LIST 200. We look for
a U2 or D2 further along in the program.
We spot a D2. It is in about the right
location. We edit it from D2 to D3 and
run.
That wasn't it! We restore the original
02 and run, then type LIST 200. But,
it has to be it. If we came from above,
we must have come down BD4. D2 gives
us the height of the visible line.
If we change D2 to D3, then BD4 must
equal BD3. Type EDIT 200 and locate
BD4. Make your change. Continue to D2
and change it, then run.
It is important that you think out
your correction. Suppose I wanted to
make the space between E and 1 one
unit wider? Type LIST 200. We know
the numeral 1 is the last character in the
line. We know that three spaces separate
each letter. Thus, we are looking for a
BR3 near the end of the program line.
The nearest BR3 is too far away, so we
look for a BR4 or BR2.
A BR4 stands out. We will change it
to BRS and see what happens. Run. Yep,
that was it. The reason it was four units
wide was that it looked better; now we
know that five units wide is even nicer
looking.
This legend was written in one con-
tinuous line. Some letters begin at the
top and some at the bottom. Five
programmers might create this line in
five different variants. I am apt to
proceed one way, and the next time I am
creating the same character/ number, I
might strike off in another direction
depending on whim. This is what makes
revising DRAW lines so tricky. It is not
easy to anticipate the workings of
somebody else's mind. C0C0 allows you
to create the legend in innumerable
ways.
That brings us to the face from last
month's tutorial. Comparing the draw-
ing with the actual C0C0 rendition, we
are struck that it is narrow — narrower
than we would prefer! The figure needs
eyes badly and that nose has to go!
For openers, let's put in some eyes
and eyebrows. Type LI5T-100. Yeah!
But where are the eyes? Run it. We look
for clues. It is almost certain that each
eye consists of ERF. Two eyes means we
are likely to find two sets of ERFs near
each other. Type LIST-20. Good news!
It looks as if the eyes were the first
feature drawn. A good way to check is
to inject an obvious pointer between 70
and E. Insert G10 or H10 and run. The
graphic is likely to be distorted, but the
line will point to the edge of the eye. We
now know where and which eye was
drawn first. We remove the pointer and
run. Now type LIST 20. On graph paper
we trace out the eyes to see in which
order they were drawn.
Luckily, we have Figure 1 from last
month's tutorial to consult. We com-
pare Line 20 with the sketch and note
the route followed: right eye to left eye
to nose to mouth. We now know we can
work on the eyes in peace.
Beginning at the inside of the right
eye, finish up the eye; move up and do
the right eyebrow; do the left eyebrow
and drop down to rework the left eye.
I sketch out my planned units. After the
first ERF, I make the insertion GUGRHDH
and run. It looks like a Cyclops, but
distortions are to be expected. I con-
tinue inserting, with BHE2R2F, and run.
Now insert BRER2F2BG and GUGRHDH.
Run it. We are off to the left. Type LIST
20. Can you see that BR3 has to go?
The original eyes were separated by
BR3. Since we covered the eyes and
eyebrows without any gaps, we don't
need that space anymore. Look at
Figure 1. What we require now is to
yank BR3 to do the top of the eye. Run.
The nose must go over one unit to the
left — maybe two units. Type LIST 20.
We see that the move from eye to nose
is BM-3,1. We try -5 in place of -3 and
run. No good! Try -4 and run.
The eyebrows seem too high. Let's
change E2 to E and F2 to F. Run. Now
it's cross-eyed. Let's increase the space
between eyebrows two units, from BR to
BR3, and run.
The nostrils are pathetic! How would
it look if we zapped the nostril and just
kept FRE to suggest a nose? We want BM-
2, 1 to replace BM-3, IDE. FRE stays, but
FNU2 goes! Now type L I ST 20. We know
D4 is the nose. Change BM-3,1 to BM-
2,1, delete DE and run. Good! Pull out
FNU2 and run. We need to change BD3
to BM+1,3.
If we made the tip of the nose wider,
R2 instead of R, then we would need BD4
instead of BM+1,3. Run. Not so hot!
Let's move the nose tip one unit to the
left. Type LIST 20. Next, type BM-3,1
and BM+1,4 to replace BM- 2,1 and BD4
and run. The nose, D4, should be one
unit to the left. Or, suppose we change
DA to M-1,4 and BM-3,1 to BM-2,1?
Run. Terrible! Restore DA and leave BM-
2,1 alone. Run again. I am not too
crazy about the eyebrows, but let them
go for now.
Let's make the face wider by one unit.
We will add one unit each to the hori-
zontal areas of the chin, top of head and
forehead. First, the chin: It is either LA
or R4. Type LIST 20 and look for either
one. An R4 is on the bottom line. We
shall put a pointer in front of R4 to see
if we are in the right place. Insert D10
in front of R4 and run. The face is
distorted, but if you look carefully you
will see we hit the location right on the
chin. Delete D10 and, while you are at
it, change R4 to R5 and run.
The forehead looks like R2. It must
be in Line 2 1 or 22. Type LIST 21. There
is no R2, but there is an L2. Let's put
a pointer, D10, in front of L2 and run.
Yes! The face is distorted, but we are in
the right pew. Remove the pointer and
change L2 to L3.
The last R3 on top of the head must
be changed to R4. Type LIST 21. An R3
150
THE RAINBOW August 1987
is down about the 130th character. We
put a pointer, D10, to verify the loca-
tion, in front of R3 and run. Right on
the money! Remove the pointer and
change R3 to R4 and run.
The left side of the shirt is one <«nit
off. It must be where it touches the neck.
The part, M-3,2 orM+3, -2, needs to be
moved over. Type LIST 21. No such
animal. Type LIST 22. There is an M-
3,2 about 70 characters into the line.
Put a pointer, R10, in front of it to see
if we are zeroed in and run. That's it!
But, what is the correction? Type EDIT
22. Remove the pointer, R10. BE looks
like the guilty party. Change it to BH and
run. Close! Type EDIT 22 and change
BH to BU. Now run.
Back to the eyebrows! Type LIST 20.
Suppose we change the first E to BE and
the second F to BF in the eyebrows?
Run. Now the eyes are not bulging.
That R5 chin should be R3. That
would change the preceding N+3,2 to
M+4,2 and the following E2 to M+3,-
2. Make the changes and run.
At this stage, I wandered away from
C0C0 and took a break. Returning
refreshed, I looked at the face more
critically and noted that the R3 lip line
needs an additional unit to balance it.
Type LIST 20. It is easy to spot, being
about 1 10 characters into the program
line. Fortunately, the movement in
front of it is BR. What is easier than
deleting the B to expose the R and
accomplishing the mission without
disturbing the shape of the face? Run.
This leaves the itty-bitty L or R dim-
ple/lower lip line. It needs to be wid-
ened to put the face into a more bal-
anced position. Type LIST 20. No
doubt, it followed the RR3. We could
change this to R4, but who is going to
inspect our work and object to our
awkward construction? We must be on
the lookout for the L that follows.
To widen L without distortion, caused
if we use L2 to add one unit, a better
method is to use NL after L. This way,
we move one unit left and return one
unit right. It doesn't affect the following
offset which, if you check it out against
Figure 1, moves up to the right jaw line.
Run.
1 don't like it! It is too wide. To try
to shorten its length, replace LNL with
GNH and run. It doesn't look especially
attractive, but I'll settle for it.
The ear could be integrated with the
sideburns by removing those angles, but
I like the suggested, stylized face.
There is one more error I overlooked.
It is a problem for you to solve. Note
that the right, inner side of the lapel
should be located one space to the left
(consult Figure 1). Make the modifica-
tion on your own initiative, then con-
gratulate yourself on mastering this
tutorial. Save FINRLF if desired.
You were subjected to many altera-
tions in this tutorial so that you would
have the confidence to rip apart and re-
arrange those pesky components in the
DRAW statements. The newcomer may be
uneasy with the graphics capabilities,
but now he knows how to debug his own
programs with every expectation of
ending up with a solid graphic.
Some of the changes we made seem
petty. When you are working on your
brainchild, they take on an aura of
importance because you want a perfect
graphic.
I hope you enjoyed having your cage
rattled and working out these little bugs
because I want to excite, challenge and
encourage your desire to create an
innovative program on your favorite
computer. □

Using the
6 ms Stepping Rate
By Dan Downard
Rainbow Technical Editor
/ have a Radio Shack ihinline disk
drive and a 64 K ECB CoCo 2 (Version
I.I), and I have been trying to increase
the stepping rate to 6 ms. I know the
disk drive can handle it because it works
at 6 ms on OS-9. I've tried POKE
55232 , : POKE 55318 , 20 but it doesn V
work.
Steven Haase
Englehart, Ontario
Steven, you are close but missing one
thing. Memory locations 55232 and
55318 are in ROM. You cannot change
ROM memory with peeks and pokes.
You have to run a program similar to
ROM RAM, which moves the ROM to
RAM and enables the 64K RAM mode
of your CoCo. I'm sure that everything
will be OK after you run ROM RAM, or
a similar program.
DLOAD Discovery
/ have a 16K CoCo 2 without disk
drives. One day while experimenting
with commands, I typed DLOflD and it
hung up. I had to reset the computer to
get the cursor back. What does the
command DLOAD do? If it does nothing,
why is it there?
Steve Nilsen
Seattle, WA
Dan Downard is an electrical engineer
and has been involved in electronics for
27 years through Ham radio (K4K WT).
His interest in computers began about
eight years ago, and he has built several
68XX systems.
DLOflD was a command to transfer
programs from one computer to
another, such as in a classroom envi-
ronment. There was a flaw in the orig-
inal ROM, and it would not work unless
the command was patched. This com-
mand has been overwritten by the CoCo
3 BASIC ROMs to add new commands.
Gook luck, Steve, and thanks for writ-
ing.
Clever Solutions
/ bought a CoCo 3 and found it
consistently destroyed every directory
when saving over the same file by
offsetting the directory entries by one
byte (sometimes the GA T was also
destroyed, sometimes it was not). When
I stopped using the high-speed poke, it
worked perfectly every time. In other
words, for reliable operation, do not use
the high-speed poke when performing
disk I/O.
VIP Desktop automatically sets the
VDG to colors that look terrible on a
monochrome monitor. Fortunately, the
program may be used to fix itself using
Disk- Zap.
Track 33, Sector 8 — change bvte 41
from FO to F8
Track 33, Sector 6 — change byte 34
from 03 to OF
Track 33, Sector 7 — change byte 1 10
from 03 to OF
Track 24, Sector 4 — start at byte 9,
replace I2s with BG 03 B7 FF22
Track 26, Sector 4 — starting at byte
85, put in BS 03 B7 FF 22 7E 4G E?
Kill CHECKG4K'-SHT and save the
following program as VIP.BAS:
10 POKE&HFFBC,0:POKE&HFFBD,
4B:UIDTH32:LOflDM"DE5KT0P"
To use Desktop, simply type
RUN "VIP". This patches everything
except Terminal (which uses both high
and low resolution screens). The low
resolution is OK (when these patches
are used). When entering the terminal
mode, simply press CLEAR-SHIFT-8 to
change the color. Now everything is
readable on a monochrome monitor.

Understanding Memory
What do you recommend for a good
CoCo memory map that would cover
BASIC 1.2 and RS-DOS 1.1? lam look-
ing for a map that comments on what
each address does and breaks it up into
the different subroutines it may encom-
pass. It would have to be in a format
that could be understood by new ML
programmers. A lot of maps use codes
for their comments that are not in-
cluded in the normal process of assem-
bly language learning.
I have looked at Disk Basic Unrav-
elled and the other books in the set, but
they are somewhat difficult for a be-
ginner to understand. What is FDC?
Merle Metzger
Tucson, AZ
I'm glad you wrote, Merle, as you are
quite typical of the beginning CoCo
user. To have a good understanding of
the CoCo, you must have a good work-
ing knowledge of both hardware and
assembly language programming. This
is no easy task for the novice. I suggest
TRS-80 Color Computer Assembly
Language Programming by William
Barden, Jr. (Radio Shack Catalog No.
62-2077) as an excellent start. By the
way, FDC stands for floppy disk con-
troller.
6809E microprocessor. I would replace
it and see if the problem disappears.
High Resolution Graphics
/ have written an assembler program
that does graphics on the CoCo 2 based
on a music input through the cassette
port, but my output on the text screen
looks a little crude. How can I get to
PMDDE 3 or PMODE A in assembler?
Joseph Weintraub
Woodside, NY
The address of the VDG in your
CoCo 2 is SFF24. Figure out the color
combination you want using the High
Resolution Graphics section of the
Getting Started with Color BASIC
manual. Load this value into Register A
and do a 5TG SFF24. If you want to see
how Microsoft did it, disassemble the
ROM at $9621.
On the Fritz
1 have a problem with Color Scripsit.
Once I accidentally pulled the pack out
of the computer while it was still on.
Now my cursor moves across the screen
randomly. I can't use Color Scripsit,
and when I press SHIFT-CLEAR, I get a
'Y' instead of a slash. What is wrong?

Keith, it sounds like you need a new
Underlining Made Easy
/;; your May 1987 column. Bill
Hodges said that he was unable to
underline the spaces between words
when using his CoCo and Telewriter 64
with a D WP-220. 1 have the same setup,
and complete underlining can be had by
adding one more embedded command
at the top of your text. Right below ^Dl
15 and ^D2 14, add ^DPS 95. When
you type a line you want underlined
completely, begin the line with a CLEA R-
I, end it with a CLEAR-2, and wherever
there is a space in the line, insert a
CLEA R-3. This causes a _ character to be
printed in each space, giving you under-
lining [hanooksjikejhis^ not this. This
also works with a Tandy D WP-230.

KISSable OS-9
Controller Attacks Halt Line Problem
By Dale L. Puckett
Rainbow Contributing Editor
■W"W 7 recently had the pleasure
^WO of meeting David C.
T T ^/ Wiens of Sardis Technol-
ogies, a man with a great idea in a brand
new hardware product at the Chicago
RAIN BOW fest. He was taking orders
for his new DMC Disk controller.
DMC stands for Dual Mode Controller.
Ifyou've ever lost halfyourcommand
line trying to type ahead while OS-9 was
accessing your disk drives, you'll appre-
ciate Wiens' new disk controller card.
You'll also appreciate it if you have had
trouble using your CoCo to gather real-
time data in a laboratory or lost large
chunks from incoming messages from
an online data service like Delphi while
OS-9 was reading a disk file you were
printing in the background.
Wiens' next statement sounded like
an excellent sales pitch, but it also made
a lot of sense. "The waste of processing
power caused by the continuous halting
of the 6809 microprocessor is up to
twice as bad with the CoCo 3 as it was
with the CoCo 2," he said. "Why?
Because the CoCo 3 can run at twice the
speed, twice as many instructions could
have been executed during the time the
6809E is halted."
Ironically, the fault does not lie with
Dale L. Puckett, who is author of The
Official BASIC09 Tour Guide and co-
author, with Peter Dibble, of The
Complete Rainbow Guide to OS-9, is a
free-lance writer and programmer. He
serves as director-at-large of the OS-9
Users Group and is a member of the
Computer Press Association. Dale is a
U.S. Coast Guard lieutenant and lives
in Rockville, Maryland.
the CoCo itself, or with OS-9. Rather,
all the blame can be assigned to the disk
controller. And unfortunately, all other
disk controllers on the market at this
time have the same problem.
To maintain full compatibility with
existing software, Wiens designed the
DMC controller with two modes. It
retains the current Radio Shack "halt"
mode, but also adds a new "no halt"
mode. In the latter mode, the DMC can
read from or write to a disk by itself
while your 6809E continues to run
independently, crunching your data or
scanning your keyboard, etc. The 6809
is only needed at the beginning when it
initiates the read or write operation and
at the end when it checks the status and
moves the data to your Color Comput-
er's main memory area.
The DMC controller comes with an
8K cache memory, but you may add up
to 32K. It uses a Western Digital
WDI773 controller chip and comes
with a version of Dan Johnson's SDisk
software, which has been modified to

Database Applications Hit Market
Two major OS-9 Level II-based data-
base applications were shown at RAIN-
BOWfest Chicago. Both CSG IMS
{Information Management System),
$169.95 from Clearbrook Software
Group, 446 Harrison St., P.O. Box
8000-499, Sumas, WA 98295, Phone:
(604) 853-9118; and Sculptor, from
Microprocessor Developments Ltd in
London and distributed at $495 from
FHL, 770 James St., Syracuse, NY
1 3202, Phone: (3 1 5) 474-7856, appeared
to be selling quite well.
We hope to take a detailed look at
these powerful database products and
feature sample applications written in
both languages during the next several
months. In the meantime, the pressure
of a book deadline forces us to restrict
this month's offering to an overview of
each program.
The CSG IMS uses a language sim-
ilar to dBase //from the IBM PC world.
In fact, its extensions move it close to
dBase III. IMS uses Balanced Tree
Indexing, which allows several users to
access your data files simultaneously. It
also means you will not need to period-
ically reorganize your data files. You
may store up to 1,073,741,824 records
in a database, and a single text field can
contain up to 32,768 characters. You
may use up to 127 unique indexes.
The CSG IMS compiler lets you
develop complex applications quickly
and easily. It contains more than 25 file-
related functions, more than 20 I/O
functions and several dozen commands
and functions that let you control the
flow of your program, perform math-
ematical operations, manipulate text
and trap errors. A unique feature lets
you convert text values to sound codes,
which means you will be able to search
for "sound alike" names. A screen I/O
program lets you build a "fill-in-the-
blanks" form on your CoCo screen.
CGS IMS will take it from there and
automatically create a database mainte-
nance program based on that screen.
An interactive environment built into
CSG IMS lets you search for important
data without writing a report program.
For example, if you need to know which
salesman sold more than $1,000 worth
of merchandise in March, you could
simply type:
158
THE RAINBOW August 1987
LIST FDR sales(3) 1000
print name, sales(3)
You drive CSG IMS through a menu
that gives you access to a text editor, file
generator, screen form generator, re-
port generator, language compiler,
language interpreter, interactive envi-
ronment and OS-9. CSG IMS applica-
tion and data files may be ported to
other versions of the program that run
on all versions of OS-9. Clearbrook
plans future implementations for MS-
DOS, the Atari ST and Amiga.
Clearbrook also has an offering that
may interest OS-9 hackers. They are
selling ER1NA, a user-mode debugger
developed by Seikou Electronics Co. of
Japan. ERINA includes a small disas-
sembler, an assembler and two dozen
commands that speed up program de-
bugging. Commands include Compare,
Dump, Examine Registers, Execute,
Fill, Goto, Input. Link, Memory Exam-
ine, Output, Protect, Quit, Search,
Transfer, Unlink, Verify, Display,
Trace, Print, Set Breakpoints, Set Dot
Variables, Evaluate and Help.
Sculptor. A Fourth Generation Lan-
guage for CoCo
Third-generation programs were
written in high level languages like
BASIC, COBOL or C. After they were
written, they had to be compiled or
interpreted. To generate a database
application, the programmer had to
oversee every last detail of the program.
Today, fourth-generation languages
like Sculptor from Microprocessor
Developments, Ltd, and FHL make the
job of generating adatabase application
program much easier. They do this by
delivering a complete set of develop-
ment tools. Each part of the set is
designed to do a particular job for the
programmer.

When you write a fourth-generation
program, you combine selected por-
tions from the existing set and tailor
them to meet your own needs. You do
not have to go back to the basics and
code every detail. Essentially, the
fourth-generation language does the
low-level coding for you.
". . . you will be able
to search for 'sound
alike' names."

For example, Sculptor includes tools
to create and maintain indexed data
files, describe data dictionaries, create
and update screen forms, write reports,
make menus, generate programs and
make inquiries into a database.
One of the beauties of the Sculptor
system is its automatic program gener-
ation. Two programs, sg and rg, create
standard programs for you automati-
cally after you have defined the record
layout and created a keyfile for your
data, sg generates a program that lets
you input, delete or amend data in the
keyfile by filling in the blank spaces of
a form on your screen, rg generates a
program for you that will produce a
printed report from your database.
While Frank Hogg awed the RAIN-
BOWfest crowd with Sculptor, his
nephew Rich and new assistant Nancy
sold many copies of DynaStar with
DynaForm. Both programs have been
rewritten in C and customized to take
advantage of the CoCo 3 and OS-9
Level 11. As a bonus for CoCo 1 and
CoCo 2 users, FHL put all older ver-
sions of DynaStar on the same disk with
the new release, including the original
version that works with any terminal
supported by the proper GoToXY mod-
ule.
The new CoCo DynaStar determines
what kind of terminal you are using by
reading a file named termset in your
SYS directory. The file termset is also
used by Microware's Scred, the screen
editor that Tandy includes in the OS-9
Level II developers package. CoCo
users don't need to worry about
termset unless they are using an exter-
nal terminal. They need only copy the
160
THE RAINBOW August 1987
SYS/termset file from the FHL Dy-
naStar distribution to their system disk.
On the other hand, you can amuse
yourself for hours just playing with the
last four parameters on each termset
line. These bytes change the color of the
foreground and background of both the
main window and the overlay windows
DynaStar uses to display its help mes-
sages. They are in this order:
1. Foreground color of help menus
2. Background color of help menus
3. Foreground color of text screen
4. Background color of text screen
If you load DynaStar first, you can
pop in and out of it quickly and observe
what happens each time you change one
of the bytes above. I experimented with
different color schemes for nearly an
hour before I made up my mind.
If you hook up a Televideo 910 ter-
minal to device 'T2 through the RS-232
pack in slot one of your Multi-Pak
interface, you will find that it works
perfectly. You'll also find lines for a half
dozen other terminals in the termset
file supplied.
DynaCalc Patches
Karl Quinn of Terminal Island, Cal-
ifornia, wrote us recently and passed
along several patches that fix minor
bugs in Version 1.00.00 of DynaCalc.
The first change fixes the problem of an
extra line feed being sent after every
carriage return when printing a report.
Specific instructions that use only
"vanilla" OS-9 commands are available
at no cost from Radio Shack Computer
Centers. The quick fix is to use Cora-
puterware's patch utility to make the
following changes:
Offset
Old
Nev
0007
80
81
0008
63
62
4BE2
26
20
Make sure you use the w command
before you exit patch, to ensure that
DynaCalc's CRC is updated. A second
bug attacks you if you use the DMP-105
or DMP-I20 Tandy printers, which do
not recognize the "Top of Form Feed"
character that DynaCalc sends out.
Change the following byte:
Offset
5000
Old
oc
New
0D
Again, don't forget to update the
CRC with the pa tch v command before
quitting.

Try OS-9 on Duane Perkins' BBS
Before You Buy
We received an interesting offer from
Duane Perkins, P.O. Box 255, Mount
Gretna, PA, (717) 964-3536, this month.
He has written a BBS system named "9-
Online" that lets CoCo owners run OS-
9 remotely. Here's how it works.
You send Perkins an alphanumeric
username and password and a one-time
non-refundable fee. He registers your
username and password, gives you an
initial allotment of disk space, sends
you terminal software you can run on
your non-OS-9 CoCo and instructions.
Your initial fee buys you three hours of
online lime. You pay the telephone
charges.
Perkins has come up with a novel idea
that could be put to good use by local
Color Computer Clubs wanting to help
their members get started with OS-9. If
a club set up a system like this on a local
phone line and made it available 24
hours a day, many new people would be
able to try OS-9 and get familiar with
it before they buy it. Go for it!
This Month's Listings
S.B. Goldberg has contributed
VMode. This handy utility lets you turn
the disk verify routine on and off on the
fly. To turn verify on, type vmode v. To
turn verify off, type vmode -v. If you
don't remember what state you left the
verify utility in, type vmode and it
reports the current state.
Greg Law is back this month with

OS-9
Level II
OS-9 MEMORY
The Problem with BASIC09
BASIC is so powerful I sometimes
almost forget that assembly lan-
guage is the ultimate language.
Getting at more than 64K of memory on
the 6809 is a challenge in any language.
It's almost impossible with BASIC09.
I don't like the dummy editor/ printer
program I showed you in the May 1987
issue. The only way I could find to start
the printer process from a BASIC09
program was the Shell command. It
worked, but it caused trouble. The
programs had to look foolish as they
chased around patching the parameters
so the shell wouldn't laugh at them
changing them back into poetry.
I didn't need the shell. The OS-9
FSFork system call woulj have done
exactly what I wanted. The problem is
that there's no way to issue the FSFork
system call from BASIC09. Or is there?
There are two ways to do a fork from
BASIC09. The easiest way is to use the
SysCal 1 procedure. (It's on Delphi and
in the OS-9 Users Group software
library. It also comes with Level II.) It's
a little harder to write a special proce-
dure to do a fork, but it will be clean
and efficient.
I'll show you how to use an assembly
language procedure to make the editor/
printer pair from May work much more
smoothly.
Peter Dibble has a bachelor 's degree in
chemistry and is currently a graduate
student in computer science. He has
worked as an applications programmer,
systems programmer and as the user
services assistant director for the Uni-
versity of Rochester Computing Center.
With Dale Puckett, he is the co-author
of The Complete Rainbow Guide to
OS-9.
By Peter Dibble
The Programs
Even when it isn't run from the shell,
BASIC09 can't deal with carriage return
characters on the command line. How-
ever, it treats line feeds like any other
character. Since a line feed generates a
new line when BAS1C09 prints it, I put
line feed characters, CHR$(10), in the
text wherever I want a new line.
The BFork procedure is an assembly
language procedure meant to be called
from BASIC09. It can be called using:
run BFork [command _ line)
or
run BFork (command _ line, op-
tional _ memory )
In both cases, BFork starts a process
running BASIC09 with the specified
command line. If you give BFork a
second parameter, it acts like the II
option on a shell command line, e.g.,
you can give BASIC09 more memory with
it.
BFork starts a BASIC09 process with-
out using the shell. This means that the
command line parameter goes directly
to BASIC09. For our purposes, that is a
good thing. It means that we can be less
careful about what we put in the com-
mand line. For instance, if the shell were
involved, an exclamation point in the
command line would have caused the
shell to try to set up a pipe. That's not
what we want at this point!
What's Going on in BFork
The first section of BFork is all
definitions. We set up the page headers
and the module header and define a
symbol for the Parameter Error code.
Except for the page header information,
identical lines will appear at the begin-
ning of any subroutine module.
After the module header, we set up
symbols for the values BASIC09 will pass
in the stack. BASIC09 puts lots of infor-
mation in the stack. Starting from the
bottom (6809 stacks grow down) we
have:
• The return address.
• The number of parameters BASIC09
is passing us. This had better be one
or two.
• The address of the command line.
• The length of the command line.
If the caller included an optional mem-
ory parameter:
• The address of the amount of extra
memory.
• The length of the amount of extra
memory (2, if this is an integer).
The next part of BFork is constant
values. There's the name of the program
(for the module header to refer to),
BFork's edition number, the string
"Basic09," and a constant zero.
Next, we get to the program itself. If
we were only passed one parameter, we
pretend that we were passed an optional
memory parameter of zero — that's
what the constant zero is for. If there are
two parameters, we use the second one
as the optional memory. At this point
we don't do anything with the optional
memory, just leave the X register point-
ing at it.
Now we worry about the length of the
command line. If it's zero, we have
problems. There has to be at least the
name of the BASIC09 procedure to run.
If it's non-zero we put it into the Y
register. It looks like it would have been
better to put the length of the command
line directly into Y, but we're about to
use it again.
OS-9 doesn't allocate extra space to
August 1987 THE RAINBOW 163
hold a process's parameters. Since
parameters are usually shot, this isn't a
problem. BFork could be passing a long
command line, so we worry about it.
Optional memory is given in pages, so
we have to convert the length of the
command line (which we cleverly left in
D) to pages and add it to the optional
memory.
From here we just set up the rest of
the values FSFork needs and do the
fork. The process that FSFork starts is
called a child. BFork waits for the new
child to end.
BFork returns with the most pessi-
mistic value it can find. If anything went
wrong in BFork, that error code is
returned. If BFork runs smoothly, it
returns whatever the child returns.
How Does This Fit in?
Editor and Printer together are
tiny. There is obviously no need for
BFork. The programs are supposed to
represent much larger programs. I gave
them dignified names to support the
fiction that they are large and compli-
cated.
Imagine complicated programs
hooked together by BFork. BASIC09 uses
almost 24K of memory, leaving 40K for
your program and data. A 56K program
won't fit in memory. If you can divide
the 56K program into a 40K part and
a I6K part and connect them with
BFork, Level II will go into action and
give you the memory you need.
Remember that we are still working
on the second simplest way to access
extra memory. The simplest way was to
use processes that have nothing to do
with each other. This way uses BFork
(or She 1 1) like a procedure call that can
only send values to the called proce-
dure. Values can't be returned. □

BARDEN'S BUFFER
Learning the Lingo
By William Barden, Jr.
Rainbow Contributing Editor
Sorry about the recent lapse in "Barden's Buffer." I've
been trapped in the internals of OS-9 trying to figure
out how things work. In any event, I'm back and ready
to use the CM-8 Color Monitor I purchased at
RAINBOWfest-Chicago. I highly recommend the RAIN-
BOWfests, by the way. There's something for everyone, the
prices are excellent, and there are plenty of free seminars. I've
attended the last few RAINBOWfests and have given
seminars on CoCo languages, a subject dear to my heart. Not
only does the CoCo support a new version of BASIC under
OS-9, called BASIC09, but it also supports two of the most
popular computer languages ever: PASCAL and C. I want to
look at computer languages in general and some of the
philosophy behind them. In addition, there are some
interesting things about using languages under OS-9 on the
CoCo.
In the Beginning Was Machine Language
By now, you all know about the 6809 microprocessor in
the CoCo. In the CoCo 3, it's the 6809E, which is simply a
faster version of the 6809. Both microprocessors use the same
instruction set. The instruction set of the 6809 is thought by
many programmers to be better than the instruction set of
the 8088/8086/80286/80386 microprocessors used in MS-
DOS systems (like the Tandy 1000 or 3000) because it's more
of a "classical" set of instructions - - more general purpose
instructions that can use a variety of addressing modes.
Machine language instructions perform very primitive
operations when compared to high-level languages. A typical
instruction sequence is shown below, which adds the numbers
from I to 10 with the result in the fi register.

Bill Barden has written 27 books and over 100 magazine
articles on various computer topics. His 20 years 'experience
in the industry covers a wide background: programming,
systems analysis and managing projects or computers
ranging from mainframes to micros.
Instructions operate at a byte or word level — eight or 16
bits of data — rather than in the floating-point format of
BASIC. Consequently, you've got to implement your own
floating-point subroutines and even design your own printer
or I/O drivers in many cases.
Machine language refers to writing sets of instruction
sequences in binary ones and zeroes, the only language that
a microprocessor really recognizes. Although it's certainly
possible to write code that way, it's very tedious. Chances are
that, in a string of ones and zeroes that represent the "add
the numbers from 1 to 10" code, you've made one or two data
entry or logical errors. Deleting, modifying or inserting
instructions means a tedious rehash of the ones and zeroes.
Assembly language is a way to make that coding less
tedious. Instead of just ones and zeroes (or the hexadecimal
equivalent), programmers write down instruction mnemon-
ics. These are abbreviations for what the machine language
instructions really do, such as flDDFI S3E84 for, "Add two one-
byte operands, one from the fi register and the other from
memory location S3E04, and put the results in the fl register."
An assembler program takes the assembly source code and
translates it into those ones and zeroes in "object code." The
object code is what is loaded and executed in the micropro-
cessor. The assembly language version of the "add the
numbers" code is shown in the listing. Everything to the right
of the 00-v.v.v line numbers is written and edited by the
programmer. The line numbers, and everything to their left,
are spewed out by the assembler program.

The CoCo has several assemblers available. Some are
"foreign assemblers," including the excellent Micro Works
assembler, but the most popular assembler is Radio Shack's
EDTASM+ on cassette or disk. This is a highly interactive
assembler written by Microsoft. It combines the assembler
proper, an editor similar to the BASIC editor and a debug
package called ZBUG, which allows you to execute and find
errors in the assembled program under programmer control.
168
THE RAINBOW August 1987
The whole package allows in-memory assembly, editing and
debugging in a nice, interactive environment.
Radio Shack no longer markets the EDTASM+ disk
assembler, even though it is indispensable for CoCo assembly
language, (The cassette version is still around, at $39.95.)
Why no EDTASM+ disk assembler? Radio Shack is driven by
what sells. If a product falls below a certain sales level, they
pull it from the catalog. There are many copies of disk
EDTASM+ floating around, however.
One reason for EDTASM+'s demise is the availability of the
OS-9 assembler. The OS-9 assembler has many of the features
of EDTASM+, especially in the editing and assembling area.
However, it does lack the interactiveness of EDTASM+ — it's
much harder to edit, assemble and debug an OS-9 assembly
language program.
The philosophy of OS-9 assembly language is different, as
well. EDTASM+ assembly language programs run "stand-
alone" without any operating system. OS-9 assembly
language programs, or modules as they are called, run under
the watchful eye of OS-9. This is a mixed blessing. Under
OS-9 you can use many of OS-9's operating system calls to
perform tasks such as reading a character or writing to the
screen. On the other hand, all assembly language code under
OS-9 must be position-independent.
Position-independent code means that references to
absolute addresses in memory, such as the S3E04 reference
above, are verboten. Instead, an instruction-addressing type
called program counter relative (PCR) must be used.
Instructions are referenced to the current program location
rather than fixed locations. The reasons for this arc well-
founded. OS-9 loads all types of program modules into
memory at one time and keeps track of where they are.
Modules must be able to operate anywhere in memory
because there are no fixed locations.
Writing code in PCR addressing format is not that difficult
(compared to normal assembly language code), but is rather
limiting and just another complexity for a beginner to
contend with. Coupled with the fact that you must know how
to use OS-9 to run the assembler, using the OS-9 assembler
is is no easy chore.
Assembly language, although difficult to learn and a
tedious language in which to program, has one great virtue.
It's extremely fast — up to hundreds of times faster than
interpretive BASIC. It will always be the language of choice
for powerful commercial applications that are meant to sell
in large volumes.
academia realized that something had to be done about all
that "spaghetti code." One proposed answer was structured
programming.
In structured programming, code is broken up into nice,
neat modules. Each module performs a well-defined function,
say, calculating a monthly payment given a principle amount,
an interest rate and a time period. There is one entry point
for each module and one exit point. Loops are indicated by
indentations of code, and there are generally no GOTOs or
their equivalents.
How is it possible to write a program without GOTOs? One
way is by providing enough commands for loops. After all,
most programs are one big loop with smaller loops inside and
nested loops within loops. Another feature is the use of
procedures. Procedures are simply the modules we've been
discussing and are very similar to subroutines. However,
procedures use parameters that are passed from a main
program or another procedure. Variables are used in the
procedure locally and may not be available outside the
procedure.
Loops
Here's an example of a loop in BASIC09:
SUM =
1 = 1
WHILE I <> 1001
SUM " SUM + I
I - I + 1
ENDWHILE
Here's another:
SUM = p
FOR COUNTER = 1 TO 1000
SUM = SUM + COUNTER
NEXT COUNTER
Both loops do the same thing: compute the sum of the
numbers from 1 through 1000. Notice one thing about this
code — it doesn't have line numbers! None of the structured
languages, including BASIC09, require line numbers, although
some, including BAS1C09, may allow optional line numbers.
Procedures
Structured languages get around the lack of line numbers
and subsequent lack of GOTOs not only with loops, but with
procedures. There is usually one main procedure that calls
many other procedures in a program. Sub-procedures may
call other procedures and so forth. Here's a typical sequence
in BASIC09:
CoCo 3 BASIC
CoCo 3 BASIC is mostly interpretive BASIC with a few
Microware add-ons for the high resolution modes of the
CoCo 3. HCIRCLE, HCLS, HCOLOR, HDRflU, HGET, HLINE,
HPPIINT, HPOINT, HRE5ET and HSET are like the counterpart
commands for the CoCo 2, as are LPEEK and LPOKE (the latter
are for extended memory). Other goodies allow error-
trapping (ERLIN, ERND, ON ERR GOTO, ON BRK GOTO) and
additional screen control (WIDTH, LOCATE).
Interpretive BASIC for the CoCo 3 is every bit as powerful
as Microsoft GW-BASIC for the IBM PC Compatible (MS-
DOS) crowd.
Structured Languages
What is OS-9 BASIC (BASIC09) like? Before answering that,
let me tell you about a controversy that's raging. There are
computer science professors who literally hate BASIC. One of
the chief reasons for this is its lack of structure. Industry and
PROCEDURE COMPUTEA
PARAM B,H
TEMP = . S * B * H
PRINT "Area=" ; TEMP
END
PROCEDURE COMPUTET
PARAM B,S
TEMP = B + 2, S
PRINT "Perimeter""; TEMP
END
REM MAIN
INPUT SIDE, BASET, HEIGHT
RUN COMPUTEA ( BASET, HEIGHT )
RUN COMPUTET! BASET, SIDE )
The first two modules are procedures, called by the two
RUN statements in the main body of code. Each procedure
has variables that are used within the procedure — B,H in
the first procedure and B,S in the second procedure. These
parameters (PflRRMs) are used within the procedure and are
not recognized within the MAIN program. The 'B' in the first
procedure is a different, local 'B' from the one used in the
August 1987 THE RAINBOW 169
second procedure. Parameters are passed between procedures
by the CALL statements. In this example, the values of BflSET
and HEIGHT are passed to the COMPUTER procedure and
become B and H. The values of BflSET and SIDE are passed
to the COMPUTET procedure and become B and S. Because
each procedure uses local variables, there is no confusion
about using variable names more than once in different parts
of the program. However, global variables are still possible
and can be used in any procedures if necessary.
The Controversy
One of the first structured languages to be widely used was
PASCAL, which was designed by a Swiss computer scientist,
Niklas Wirth. It was developed for computer science use and,
presumably, was easy for students to use. An example of
PASCAL code to do the "add numbers" problem is:
var
sum, I : integer;
begin
I := 1;
while I <> 1001 do
begin
sum :* sura + I;
I :- I + 1;
end;
writeln ( 'The sura of 1 to 1000 is ", sum ) ;
end.
You can see that pascal is somewhat "BASic-like" but uses
many of the elements of a structured language — indented
code, WHILE loops, etc.
Another characteristic of structured languages, whether
BASIC09 or others, is that the variables are strongly typed. In
interpretive BASIC, you can use any name for a variable and
really don't have to be concerned about whether the values
held in that variable are integer (-32768 to 32767) or floating-
point (values such as -87.88 or 564.002). In most structured
languages, however, variables must be declared according to
type, i.e., whether they are integer variables, single-precision,
character or string variables, and so forth.
BASIC09
All of this sets the background for a description of BASIC09,
the BASIC language used with OS-9. BASIC09 is definitely a
structured language; it has optional line numbers, WHILE
loops, procedures and data types, and it supports indenta-
tions. In addition, it has its own built-in editor, which is both
line- and string-oriented.
BASIC09 is a compiler rather than an interpreter. The
Extended BASIC interpreter used in the CoCo 3 processes
BASIC programs a statement at a time. Each time through a
statement, the interpreter asks, "What is this statement?" and
"What are the variables?" Then it goes through methodically
to search for the variables, compute expressions, and
implement the BASIC statement before moving on to the next
statement. If two more statements are processed and a return
is made back to the original statement (as in a loop), the
processing starts over from the beginning as if the interpreter
had never seen the statement before. All of this processing
of the BASIC text takes a great deal of time, so interpretive
BASIC is fairly slow.
Compiled BASIC, however, operates differently. Rather
than processing each statement every time it is encountered,
the BASIC compiler makes one pass through all the statements
from beginning to end (not as the program flows). At the end
of this pass, the compiler has decoded much of the code into
an assembly language or machine language form. This object
code now executes much more rapidly than the interpretive
170 THE RAINBOW August 1987
version because much of the processing has already been
done.
In general, compiled BASIC is much faster than interpretive
BASIC. Under OS-9, though, BASIC09 is a lot slower than you
would expect — only three or four times faster than
interpretive BASIC in many cases. Why? The overhead of OS-
9 has a lot to do with the speed — there's a lot going on in
OS-9 and some of it is not done efficiently.
Running the BASIC09 compiler requires a different ap-
proach from CoCo Extended basic. Instead of being able
to immediately edit and execute a line of BASIC code, a
program under BASIC09 must first be recompiled. This makes
debugging much more tedious — the quick interactiveness
you find with Extended Color BASIC is not there, nor are the
debugging tools, although BAS1C09 has a trace mode and some
interactive hooks.
On the other hand, because BASIC09 is a structured
language, it offers certain advantages. It's easy to read and
maintain code, has modules (procedures) that can become
part of a library of modules to be used at will, and has some
compatibility with other structured languages.
It's interesting to note recent developments of BASIC in the
MS-DOS world that point to how structured languages are
being received. Microsoft developed GW-BASIC, a version of
interpretive basic that runs on MS-DOS systems and
includes just about every convenient command that is
possible to stick into a BASIC interpreter (including software
interrupts for keys, communications data and error-
trapping).
Microsoft also has a basic compiler that is compatible with
the commands found on their basic interpreter. It allows you
to write a program in interpretive BASIC, use the great
interactiveness of the interpreter to debug the program, and
then compile the program for high-speed operation.
Not too long ago, Microsoft also introduced a new
compiler called Quick BASIC for MS-DOS machines, which
not only recognizes GW-BASIC commands, but also provides
structured programming commands, such as WHILE'WEND
(looping, also in GW-BASIC), IF'THEN/ELSEIF (a type of
CASE statement), and DO UNTIL (another type of loop). The
result is a basic language very similar to BASIC09 in a highly
interactive environment.
Just a few months ago, Borland International brought out
its version of a structured BASIC called Turbo BASIC. This
BASIC also recognizes the GW-BASIC commands, but provides
a structured programming format and commands as well.
With premier developers like Microsoft and Borland
making these efforts, it seems structured programming for
BASIC is alive and well. BASIC is changing to be competitive
with the current structured languages like PASCAL and C!
More on PASCAL
We've seen a brief example of pascal, but let's look a little
further into it. PASCAL has achieved a great deal of interest
as a language because of its use in computer science curricula,
but it is not widely used in industry. Languages such as COBOL
(Common Business Oriented Language) and FORTRAN
(Formula Translator) both see a great deal more use than
PASCAL. Interestingly enough, both are almost 30-year-old
languages, which says something about being there first.
PASCAL is widely used on micros, though. One of the
reasons for this is the huge success of Borland International's
Turbo PASCAL. This is a PASCAL compiler for MS-DOS
systems such as the Tandy 1000 or IBM series. Two reasons
for Turbo's success are the high degree of interactiveness in
the compiler — it has a built-in editor — and the raw speed
of compiled programs.
Unfortunately, there is no Borland equivalent for OS-9.
The PASCAL compiler under OS-9 is certainly adequate, but
not exciting. It's a compiler like many compilers: no built-
in editor, no interactive debugging tools, and cryptic error
messages. Also, there's a great deal of overhead to compile
even short programs under OS-9. Whereas Borland's Turbo
compiles in a few seconds, OS-9 PASCAL requires a few
minutes. As I say, though, this is typical for most compilers.
Here's another sample of a pascal program. This one
computes the area and perimeter of a triangle in similar code
to the preceding BASIC09 example.
( program to compute area and perimeter of a triangle)
Program Triangle
Var
Side, Base, Height : real;
Procedure ComputeA;
var
Temp : real;
begin
Temp := 0.5 * Base * Height;
writeln (*Area=', Temp);
end;
Procedure ComputeP;
var
Temp ; real ;
begin
Temp := Base + 2 * Side;
writeln ( 'Parimeter=' , Temp);
end;
(maan)
begin
writeln ('Enter Side, Base, Height');
readln (Side, Base, Height) ;
ComputeA;
ComputeP. -
end.
The C Language
C is another language of the same ilk as BASIC09 and
PASCAL. It's highly structured and has many of the same
commands and capabilities as PASCAL. C has a reputation
as a systems programmer's language because it gets down to
the nitty-gritty, allowing programmers to perform bit
operations. It has become very popular on micros, and many
applications that would formerly have been done in assembly
language are now being done in C.
Here's a sample program in C — the same application as
previously illustrated:
/* Program to compute area and perimeter of triangle */
float Side;
float Base;
float Height;
compute_area ( )
(
)
float Temp;
Temp = J5.5 * Base * Height
printf ("Area=%f\n", Temp) ;
compute_perimeter ()
I
float Temp;
Temp - Base + 2 * Side;
printf ("Perimeter=%f\n", Temp);
)
main ()
(
printf ("Enter Side, Base, Height\n");
scanf ("%f %f %f", iSide, SBase, SHeight) ;
compute_area ();
compute_perimeter ( ) ;
)
You can see from the example that C has the same general
appearance as PASCAL. Also obvious is that C has "type

Our
Fourth
Adventure
Contest
Time passes quickly as you use your nimble fingers to escape
the very passion that consumes you. Thoughts are fleeting at
a time in which you need them most. The spidery web of
mystery and intrigue you have spun is now entangling you. Every
breath you take . . , Every move you make ... Is it correct? Will it even
accomplish the task at hand? Is there any time left?
No, we don't mean to imply time is nearly up for our Fourth
Adventure Contest. Plenty of time remains. However, the final
deadline for your entry in this contest is August 15, 1987 — a date
that is rapidly approaching. So, you'd better get started soon, if you
haven't already begun,
What? No ideas, you say? Just take a look around you! Your
everyday life presents you with hundreds, Just sit down and start now!
We await the very best you have to offer. If you want some pointers,
check out "The Adventure Writer's Toolkit" (April 1985, Page 105) by
Eric W. Tilenius. Or, for another helping hand, see "The Adventure
Processor" (August 1986, Page 26) by Bill Cook. These articles, and
many more, are just what you need to get started on the right track.
Your Adventure can be written for a 4K early model CoCo, or it
can be written to take advantage of all the features in a 51 2K CoCo
3. It can be written under Disk basic, or it might be a creation in
BASIC09.
Judging: The judges of the Fourth Rainbow Adventure Contest will be looking lot several
things in each entry. In addition to ensuring each submission Is complete, they will consider
the following:
• Originality • Vocabulary and Grammar
• Creativity • Responsiveness
• Programming Efficiency • Level of Challenge
• Clarity of Instructions • Enjoyment
• Ease of Use
The judges will also be concerned with the "punishability' of each Adventure. A shorter
program is easier to fit into print (both in THE RAINBOW and any subsequent Adventure
book) as well as being easier fa the reader to type in. While the use of graphics tends
to enhance any program, graphics are not necessary for an Adventure to win. The winning
enhy will be chosen for its unique appearance. Make your Adventure stand above the
rest!
RULES: your submission should include all programs and information needed to set up and
run the Adventure. All programs must be sent on tape or disk with several saves of each
program including at least one ASCII save. If an Adventure cannot be loaded, it cannot
be judged. We will not type in even the shortest of programs! Hard copy of all program
listings and instructions must also be included. If your Adventure uses machine language
routines, all souice code, as' well as assembled object code, should be included on the
tape or disk. Indicate the minimum CoCo system required to run your Adventure and
include a complete solution!
Please, don't use packed lines that can't be USTed or LLISTed for the benefit of our readers.
Your program should run on standard Radio Shack equipment without requiring any
special modifications and should not rely on commercial software for its execution. The
only exception is the use of the OS-9 operating system (Level I and Level II) and BASIC09.
If your Adventure uses graphics, make sure the graphics are self-contained. In other words,
don't submit a program that loads several different graphics screens unless those graphics
are created by a publishable program included in the submission.
In summary, send a complete package. Put the accompanying article, documentation,
listings, complete instructions and solution, and cover letter on paper. Include your name,
address and telephone number on each page of all materials. Be sure to write-protect
your disk or punch out the tabs on your cassette to avoid accidental erasure, and label
each with the name of the program(s) and your name and address. As In any contest,
pockaging does make a difference.
Your entry must be postmarked no later than August 15, 1987, In error-free condition. Each
entrant will receive a free pass to the RAINBOWfest of his or her choice. You may also win
one of fhe many prizes donated by our generous advertisers as well as have your program
published in the rainbow. So, get a move onl Write it up, put it together and send it
to:
Adventure Contest Editor, Rainbow Magazine, 9509 U.S. Highway 42,
P.O. Box 385, Prospect, KY 40059.
Additional Rules: All entries must be original, unpublished and unmarketed works (no
"conversions"). No programs that have been placed in the public domain are eligible.
All entries become the property of Falsoft, Inc., publisher of the THE RAINBOW. The decisions
of the judges will be final. Duplicate prizes will be awarded in the event of a tie. Winning
entries will be featured in a future Issue of the rainbow.
Prizes: Following is partial list of the prizes the winners of our
Fourth Rainbow Adventure Contest will be receiving. And,
many more prizes are being donated each day!

variables" — variables must be explicitly declared as int
(integer), float (floating-point), char (character), and
others. In C, a program is subdivided into procedures that
are called from the main program or from other procedures.
No line numbers are used, and there is no GOTO command
in the language. Although not obvious from this example,
C has the same type of loop control as in other structured
languages — WHILE loops, FOR loops, and DO/WHILE loops.
The scanf and printf commands take the place of PASCAL
READ and WRITE commands and use special characters for
formatting action, reminiscent of some of the formatting in
FORTRAN programs.
C is so popular that both Borland and Microsoft are
rushing to put out high-speed C compilers for MS-DOS
systems. The only version of C we have available for the
CoCo is the Microware C compiler. Like the pascal
compiler, this is a typical C compiler — it operates from a
previously edited source file, contains most of the standard
features found in C, and is somewhat slow in compilation.
Still, it works well in the OS-9 environment, and we can thank
Radio Shack that it is available.
Other Features of BASIC09, PASCAL, and C
All three languages allow numeric, string and multi-
dimensional arrays. Arrays in BASIC09 and PASCAL must be
fixed in size. In C, the arrays may be dynamic. The size of
the arrays may change as the program requires it.
User-defined (enumerated) variables can be used in PASCAL
and C. Suppose you wanted to define computers of a certain
type. You could define a set of variables called COMPUTER that
included the items Tandy_1000, IBM_PC, Rpple_IIG5 and
Cray_XMP.
Linked lists and trees may be processed in PASCAL and C
by the use of a special data format called pointers. Linked
lists are advanced data structures that build a list of data
elements, each element having data and a pointer to the next
data element in the list. The pointers may be easily changed
to insert, delete or modify items in the list.
Functions or procedures can have local variables, as
mentioned before. This makes each procedure in the three
languages a stand-alone module that does not have to be
rewritten with new variable names for a new program.
Another related feature found in all three languages is
recursion, the ability of a procedure or function to call itself.
Recursion can produce elegant code, as in this C example to
find factorials:
long int factorial (x)
int n
(
long int answer;
if ( X — p )
result = 1;
else
result = x * factorial (x-1) ;
return (answer) ;
)
Here, the function factorial calls itself from within the
function. (You might look upon this as a picture of a man
reading a newspaper, which contains a picture of a man
reading a newspaper, etc.) Is recursion useful? Not nearly as
useful as you might think, because it consumes huge
quantities of memory in building a stack of return addresses
and data. On top of that, it has a great deal of overhead.
However, the code is elegant.
OS-9 Language Documentation
Microware documentation on PASCAL and C is terrible. It's
summed up in these words from the OS-9 PASCAL reference
manual: "Either you know PASCAL, or you don't." The
reference manuals don't claim to be courses in PASCAL or C
programming, and I can understand why tutorial informa-
tion isn't included. However, operating information is of a
more generic nature and does not address the problem of
"Should you use a structured
programming language or
interpretive Microsoft/
Microware BASIC?"
using the compilers on the CoCo. Useful information is hard
to find or nonexistent.
The BASIC09 portion of the Color Computer 3 operating
system reference manual, however, is another story. Written
by Radio Shack's R. Bartly Betts, formerly a RAINBOW
contributing editor, it does an excellent job covering BASIC09.
You should have a much easier time learning this language
than stumbling through the forests of PASCAL or C.
Conclusions
If I sound a little tough on the compilers for the CoCo,
I really don't mean to be. Here's a truly inexpensive machine
capable of multitasking with relatively high resolution
graphics and with three of the most popular higher-level
languages available for it at rock-bottom prices. Since I love
the CoCo, I only wish we had the equivalent to Turbo
PASCAL, QuickBASIC and Turbo C to run on the system.
An easy-to-use compiler would make the task of coping with
OS-9 a great deal less frustrating.
However, we don't have these products and must use the
existing BASIC09, PASCAL or C compilers. The fact is, once
you've cut through all of the preliminary procedures to
assemble a working disk for compilations, learned the quirks
of the system, and put in some time studying the language,
you have the ability to compile some pretty neat programs
in the language of your choice.
I think the crux of the problem here is this: Should you
use a structured programming language or interpretive
Microsoft/ Microware BASIC? Certainly, if you're going into
computer science or business applications programming,
you'll have to know a structured language like PASCAL or C.
On the other hand, it's possible to use "street BASIC" with
line numbers and still crank out some pretty good, efficient
programs. Anyone capable of writing large programs in non-
structured BASIC should be capable of using the structured
languages, as well. Writing programs in structured languages
seems to produce very "wordy" programs that often are
slower than they should be. BAS1C09 may be a good compro-
mise between the ease of use of some of BASIC commands
and functions, and a well-structured language.
In any event, BASIC09, PASCAL and C are inexpensive and
available on the CoCo under OS-9. Try your hand at these
languages and find the one that appeals to you. Don't forget
assembly language, either — it's worth the grief and agony
to get the high speed. In future columns, we'll try to provide
coverage of not only pascal, C and BASIC09, but assembly
language on the CoCo as well. Believe it or not, there's a lot
of common ground among all these languages. /R\

How To Read Rainbow
Please note thai all the basic program listings in
THE rainbow are formatted lor a 32-character
screen — so they show up just as they do on your CoCo
screen. One easy way to check on the accuracy of your
typing is to compare what character "goes under" what.
If the characters match — and your line endings come
out the same — you have a pretty good way of knowing
that your typing is accurate.
We also have "key boxes" to show you the minimum
system a program needs. But, do read the text before
you start typing.
Finally, the little disk and/or cassette symbols on the
table of contents and at the beginning of articles
indicate that the program is available through our
RAINBOW ON DISK Or RAINBOW ON TAPEService.
An order form for these services is on the insert card
bound in the magazine.
What's A CoCo?
CoCo is an affectionate name that was first given to
the Tandy Color Computer by its many fans, users and
owners.
However, when we use the term CoCo, we refer to
both the Tandy Color Computer and the TDP System-
100 Computer. (While many TDP-100s are still in
service, the TDP Electronics division of Tandy no longer
markets the CoCo look-alike.) It is easier than using
both of the "given" names throughout the rainbow.
In most cases, when a specific computer is men-
tioned, the application is for that specific computer.
However, since the TDP System-100 and Tandy Color
are, for all purposes, the same computer in a different
case, these terms are almost always interchangeable.
and press enter to remove it from the area where the
program you're typing in will go.
Now, while keying in a listing from the rainbow,
whenever you press the down arrow key, your CoCo
gives the check sum based on the length and content
of the program in memory. This is to check against the
numbers printed in the rainbow. If your number is
different, check the listing carefully to be sure you typed
in the correct basic program code. For more details
on this helpful utility, refer to H. Allen Curtis' article on
Page 21 of the February 1984 rainbow.
Since Rainbow Check PLUS counts spaces and
punctuation, be sure to type in the listing exactly the
way it's given in the magazine.

OS-9 and RAINBOW ON DISK
1) Type load dir list copy and press ENTER.
2) If you have only one disk drive, remove the OS-9
system disk from Drive and replace it with the OS-
9 side of rainbow on disk. Then type chd'd0
and press enter. If you have two disk drives, leave
the sytem master in Drive and put the rainbow
on disk in Drive 1. Then type chd'dl and press
enter.
3) List the read . me . f i rs t file to the screen by typing
list read. me. first and pressing ENTER,
4) Entering di r will give you a directory of the OS-9
side of rainbow on disk. To see what programs
are in the cmds directory, enter di r cmds. Follow
a similar method to see what source files are in the
SOURCE directory.
5) When you find a program you want to use, copy it
to the CMDS directory on your system disk with one
of the following commands:
One-drive system: copy dO'cmds' filename 'd0'
cmds' filename -s
The system will prompt you to alternately place the
source disk (RAINBOW ON DISK) or the destination
disk (system disk) in Drive 0.
Two-drive system: copy 'd l 'cmds' filename 'd0'
cmds' filename
Once you have copied the program, you execute it
from your system master by placing that disk in Drive
and entering the name of the file.

Rainbow Check Plus
The small box accompanying a program listing in
the rainbow is a "check sum" system, which is
designed to help you type in programs accurately.
Rainbow Check PLUS counts the number and values
of characters you type in. You can then compare the
number you get to those printed in the rainbow,
On longer programs, some benchmark lines are given.
When you reach the end of one of those lines with your
typing, simply check to see if the numbers match.
To use Rainbow Check PLUS, type in the program
and save it for later use, then type in the command RUN
and press enter. Once the program has run, type new
The OS-9 side ol rainbow on disk contains two
directories: CUDS and SOURCE. It also contains a file,
read .me. first, which explains the division of the
two directories. The CMDS directory contains executa-
ble programs and the SOURCE directory contains the
ASCII source code for these programs. basico9
programs will only be offered in source form so they will
only be found in the SOURCE directory,
OS-9 is a very powerful operating system. Because
of this, it is not easy to learn at first. However, while we
can give specific instructions for using the OS-9
programs, you will find that the OS-9 programs will be
of little use unless you are familiar with the operating
system. For this reason, if you haven't "learned" OS-9
or are not comfortable with it, we suggest you read The
Complete Rainbow Guide to OS-9 by Dale Puckett and
Peter Dibble.
The following is not intended as a course in OS-9. It
merely states how to get the OS-9 programs from
rainbow on disk to your OS-9 system disk. Use
the procedures appropriate for your system. Before
doing so, however, boot the OS-9 operating system
according to the documentation from Radio Shack.
The Rainbow Certification Seal is our way of helping
you, the consumer. The purpose of the Seal is to certify
to you that any product that carries the Seal has actually
been seen by us, that it does, indeed, exist and that we
have a sample copy here at the rainbow.
Manufacturers of products — hardware, software and
firmware — are encouraged by us to submit their prod-
ucts to the rainbow for certification. We ascertain
that their products are, in actuality, what they purport
to be and, upon such determination, award a Seal.
The Seal, however, is not a "guarantee of satisfac-
tion." The certification process is different from the
review process. You are encouraged to read our reviews
to determine whether the product is right for your
needs.
There is absolutely no relationship between advertis-
ing in THE rainbow and the certification process.
Certification is open and available to any product per-
taining to CoCo. A Seal will be awarded to any com-
mercial product, regardless of whether the firm adver-
tises or not.
We will appreciate knowing of instances of violation
of Seal use.

Dr. Preble's Programs
Striking A Blow For
Freedom is nothing else but a chance to be better .
— Albert Camus
*** Mental Freedom
***
for CoCo 2 and 3!
(Will nol work wilh CoCo 1 )
A Thought-Controlled Video Challenge
We call il The Preble Thoughtware.
DOES GREEN BLOOD flow in your veins like Mr. Spock? Is your mind well
ordered? Or is your mind a mass of conflicting emotions like most
humans?
THOUGHTWARE may answer these questions and more.
IMAGINE! Some day, a computer so advanced that it responds to your very
thoughts and emotions. Imagine, some day, thought-controlled
graphics: levitation and materialization!
PLUG IN YOUR MIND and UNHOOK YOUR JOYSTICKS — that day is
now! The Radio Shack Color Computer has many ad-
vanced capabilities, just waiting to be tapped. Dr. Preble's
Programs combines the advanced technology of the CoCo
with the amazing Radio Shack BIOFEEDBACK MONITOR
to bring you "Preble Thoughtware."
THOUGHT-CONTROLLED VIDEO CHALLENGE? Unlike any
video game you have ever played, Thoughtware tests your
ability to handle stress, to remain calm under adverse
circumstances.
LIGHTNING FAST reflexes will do you no good here, unless you
first tame the fickle dragon of your mind.
DO YOU HAVE SELF-CONTROL? Many people can keep a
"Poker Face" even when they are worried so that others
may not notice; but can you really stop the worry itself? Thoughtware
will find out!
AND IT TALKS! Did you know that the CoCo can produce incredibly realistic
digital speech without a special speech synthesizer? And I mean really
high quality speech! Forget the mechanical robot voice. This voice
quality is so good, it sounds human! Honest. Best of all, no extra
hardware is needed for speech. None. The CoCo produces this amazing
digital speech all by itself (with a wee bit of programming by Dr. Preble).
THOUGHTWARE — Next time your friends ask what your computer can do,
show them the Preble Thoughtware!

*** Basic Freedom ***
for The Color Computer 3
(with versions for CoCo 1 & 2)
A Full Screen Editor for BASIC Programming
We call it EDITOR 3. Chris Babcock wrote a pure, efficient Machine Language
program to open a new dimension of ease and power for anyone typing in
a BASIC program.
Here are your BASIC Freedoms!
FULL CURSOR MOVEMENT — Use the arrow keys to move anywhere on a
screen. If you are using a Color Computer 3, then even the 40 or 80
column screen is supported!
INSERT, CHANGE or DELETE CHARACTERS anywhere on the
screen. Simply move to what you wish to change, change
it and continue working!
LOWERCASE COMMANDS are OK! EDITOR 3 lets you type in
lowercase any time or all the time. Lowercase command
words are automatically translated to uppercase for BASIC.
Of course, lowercase text within quotes stays lowercase.
This is great when typing wiht the CoCo 3's 40 or 80 column
mode with true lowercase!
MERGE LINES within a program with just a few keystrokes!
AUTO KEY REPEAT — Hold down any key and it will repeat.
INVISIBLE — Once EDITOR 3 has been loaded in, it is activated
with a single keystroke! It hides itself out of the way of other programs
and can be turned off any any time. Pressing RESET will not hurt
EDITOR 3!
EASY TO USE — Installation takes seconds! Well-written goof-proof manual
included.
COCO 1 & 2 — Yes, even though this program was conceived for the powers
of the new CoCo 3, we still support the previous Color Compilers. They
too. need their BASIC Freedom!
EDITOR 3 — So easy and handy, you'll never want to run your CoCo without
it!
Available on DISK only for CoCo 3 @ $29.95 * s/h
CoCo 1/2 version can not support 40 or 80 column screens. CoCo 1/2 version
is available on TAPE for $27.95 * s/h or DISK for $29.95 + s/h.
